How does cosmetic laser teeth whitening work?

Having a white smile is a symbol of health and beauty. It can boost your self-esteem and confidence. However, achieving shiny and bright teeth requires a lot of care. Many times the daily brushing, flossing and mouthwash are not enough. You may need to take further steps in order to get the whiter teeth and smile you desire.

There are various teeth whitening options available in Singapore. You can find millions of at-home whitening products online and at brick-and-mortar stores. But if you really want to achieve quick and impressive results then it could be better to consider professional or in-office teeth whitening.

In this article, we will take a closer look at laser teeth whitening. This is a type of chairside whitening which involves the use of a laser device. We will discuss how this dental treatment works, what benefits it offers, and how it is different from other teeth whitening treatments.

What is laser teeth whitening?

Laser teeth whitening is a type of in-office whitening treatment. In this procedure, the dentist uses a bleaching gel and laser device in order to reduce stains and make your smile appear whiter.

This type of professional teeth whitening is a good option for those who are seeking a quick fix and a rapid turnaround on their bleaching. The treatment can successfully remove external stains or those stains that affect the outer layer of the tooth. You normally get them as a result of drinking coffee and red wine or eating too much dark-coloured food.

In addition to eliminating extrinsic (external) spots, the laser procedure may be beneficial for improving the appearance of intrinsic stains. These are spots that you can get as a result of age, trauma or medical treatments. They develop on the inside of the teeth, at the deeper layer of the enamel and the dentin and are usually more difficult to remove.

How does laser teeth whitening work?

Laser teeth whitening is usually a quick appointment, it is around an hour long. It can be carried out by either a dentist or a dental hygienist.

Here's what to expect when you visit the dental clinic for your teeth whitening procedure.

• First, your doctor will ask you to wear glasses to protect your eyes.
• Then, he or she will place a protective layer of plastic on your gums to avoid irritations.
• Next, your provider will apply a bleaching gel, such as hydrogen peroxide or carbamide peroxide, on your teeth.
• Following that the dentist will use a laser to activate the gel.
• The laser light will quickly pass over your teeth, activating the particles within the gel. This process usually takes a few minutes.
• Lastly, your provider will remove the protective plastic and flush out the bleaching material.

The laser teeth whitening procedure is usually not painful. However, there is a great chance of experiencing discomfort and tooth sensitivity during the first 2-3 days after the treatment.

What are the benefits of laser teeth whitening?

Here are some of the advantages of getting laser teeth whitening treatment.

• Laser teeth whitening works much quicker than at-home teeth whitening treatments.
• It provides more dramatic results.
• With this treatment, you can achieve longer-lasting results, up to 3 years.
• It can treat both extrinsic and intrinsic stains.
• It is a safe teeth whitening procedure performed at the dental office by trained professionals.

However, laser teeth whitening comes with some downsides as well. In some cases, this bleaching technique can irritate your teeth and gums.

How long does laser teeth whitening last?

Laser teeth whitening is usually a long-lasting solution. Your teeth may appear brighter for as long as 3 years, where the effect of teeth whitening strips and home whitening kits typically wears off after about six months. This is because laser teeth whitening as well as other professional treatments uses a higher-concentration bleaching agent. Read our post on how long do teeth whitening treatments work for more information.

However, your teeth will remain brighter for longer in case you take proper care of them, otherwise, they may become discoloured sooner. It is essential that you practice good oral hygiene, avoid smoking and limit the consumption of staining foods and drinks.

Also, after you have your teeth whitened, your doctor will give you some aftercare instructions that you must follow for the first 48 hours. Your teeth will be very prone to blemishes right after bleaching. That is why you will be advised to go to the so-called white diet (eating foods that are white in colour) to prevent discolouration.

What are the risks of laser teeth whitening?

One of the biggest risks associated with almost any teeth whitening treatment is increased tooth sensitivity. Professional teeth whitenings are more likely to cause sensitive teeth. This is because, in these procedures, dentists normally use stronger bleaching materials in order to quickly and efficiently whiten your teeth. However, tooth sensitivity following whitening treatment is usually temporary and will go away in a few days. To reduce this risk, it is critical to avoid acidic foods and beverages during your recovery.

Additionally, teeth whitening can lead to loss of fluoride and mineral in teeth, pulp damage, decay, and erosion of the teeth enamel. These side effects are relatively rare, but still exist.

Make sure you discuss all possible risks and complications with your dental provider before getting teeth whitening treatment.

How much does laser teeth whitening cost in Singapore?

The cost of laser teeth whitening procedures in Singapore varies greatly, starting at $500 and rising to $1300. In general, how much you will pay depends on the dental clinic you choose. It goes without saying that the cost of the teeth whitening in private clinics is higher than the cost of whitening services in public clinics. However, patients often prefer private clinics due to insufficient public availability or because they want to receive a higher quality of care.

Another thing to be aware of is that laser teeth whitening treatments in Singapore are typically much more expensive compared to take-home teeth whitening kits.

How does laser teeth whitening differ from other teeth whitening methods?

The laser procedure uses a laser and a bleaching agent together, which is one of its main differences from other treatment methods. The laser device activates the particles within the gel, breaking down the staining molecules quickly. In addition, the concentration of the gel used during laser teeth whitening is higher than that used in at-home teeth whitening treatments.

Laser teeth whitening vs bleaching

Laser teeth whitening is actually a variant of bleaching. It involves the use of a bleaching agent which is activated with a laser device. During regular bleaching, on the other hand, the provider applies the bleaching gel to the teeth and after appropriate exposure time it is removed and the teeth are rinsed with water.

Laser teeth whitening is usually a little bit more expensive than regular bleaching. In terms of outcomes, there is no significant difference - both treatments are effective and can improve the colour of your teeth.

Laser teeth whitening vs Zoom

Laser teeth whitening and Zoom are actually quite similar treatments. Zoom also includes the use of a bleaching material, but instead of laser, it uses light to activate the gel. The treatment does not expose teeth to much heat as the laser does, so it might be a better option for patients with sensitive teeth. Zoom is also considered to whiten teeth quicker than laser.

Teeth whitening gel vs Laser

Bleaching trays are custom-made devices which you can get from your dentist. This teeth whitening treatment usually requires more than one dental visit. On your first appointment, the dentist will take a mold of your teeth and then send it to a laboratory to have your devices made. You should get your trays on your second visit. Along with them, you will also be given a bleaching gel. You will usually need to wear the trays over a two-week period or longer to have a gentle, gradual whitening effect.

This treatment is normally at a more affordable price than laser teeth whitening. However, the procedure takes longer and requires more applications. In addition, the results of teeth whitening trays normally wear off faster than those of the laser treatment.

Best laser teeth whitening in Singapore

Looking for the best teeth whitening services in Singapore? With so many dental clinics and providers, it might be difficult to choose where to book your appointment. Here are some tips that may help you make the right decision.

• Find out how laser teeth whitening services rate online. Don't just Google "laser teeth whitening near me" and pick the first clinic that comes there. Go through several pages and find different providers in your city. Then, read the online reviews of each clinic or dentist that you are considering visiting.
• Ask your friends and family for recommendations. This was how people found the best healthcare providers before there was a flood of reviews on the internet. You can ask family members, friends, or coworkers about a teeth whitening clinic in Singapore they trust.
• Ask for before and after photos. Many cosmetic dentists take before and after photos of their patients. Some of them may put images on their websites so that you can see real examples of their work. However, if the dentists you choose do not have photos on their websites, you can go to their clinic and ask them to show you some.

And remember, the most important thing is to find a dental provider you feel comfortable with.

Frequently asked questions about Laser Teeth Whitening

Everybody cherishes that pearly white smile, but nowadays there are some barriers to it. A number of factors play a role in teeth discolouration. Many beverages, like red wine, coffee, tea and acidic juices can cause teeth to develop stains. The same can be said about pigmented foods that leave a mark on the enamel of your teeth. Some medications and the natural ageing process also impact tooth discolouration.

The good news amidst all this is there are ways to prevent tooth discolouration. You can easily remove stains that come from foods or drinks, and even some of the tougher ones that penetrate the enamel with the right in-office whitening treatment by your dentist. In the following guide, you will find out more about the type of stains that make your teeth less white and what steps you can take to prevent that.

What type of stains can discolour your teeth?

Dentists identify three groups of stains on tooth enamel.

• Extrinsic stains - this type of tooth discolouration occurs on the outside part of the tooth. When the enamel layer is exposed to beverages and foods, it can turn yellow or brown. Some lifestyle choices also cause these stains, such as smoking and chewing tobacco. Poor dental hygiene, i.e. not brushing and flossing teeth can be a major culprit too.
• Intrinsic stains - these occur when the dentin, i.e. the inside of the tooth turns brown or yellow. Medications are a likely cause for this, as is internal injury or trauma of the tooth. Tooth decay or excessive use of toothpaste and whitening agents with too much fluoride are also known reasons for intrinsic stains. Because this is a type of discolouration ingrained within the structure of the teeth, it can be more difficult to remove and requires some assistance from a dental professional.
• Age-related teeth staining - extrinsic and intrinsic causes both play a role here. With age, the dentin underneath the enamel tends to become yellow. And because the enamel tends to become thinner, causing food and drinks can lead to more stains on your teeth.

How to prevent coffee stains on teeth?

Coffee is, without a doubt, coffee is a favourite drink to many individuals, who cannot imagine starting the day without a cup. However, it can also stain the tooth surface and alter the colour of your teeth from pearly white to more yellow. White teeth may not stay white for long after drinking coffee. There are a few strategies that can keep your teeth presentable, even if you are an avid coffee drinker.

• Use a straw - the goal of a straw is to minimise the contact of staining beverages with your teeth. Drinking coffee through a straw
• A little cream may not be a bad idea - researchers have found that a little milk has a neutralising effect on the compounds affecting the tooth enamel.
• Brush/rinse after drinking - another one of the popular tips to prevent stains after drinking coffee is to brush your teeth soon afterwards, or at least rinse thoroughly.
• Use whitening products - if the previous methods do not work, you can always rely on some over-the-counter whitening products to turn your teeth white again. Whether that be whitening trays or whitening gel, you can choose from a variety of products to whiten your teeth at home or with the aid of your dentist.
• Don't forget about quality oral hygiene - even though there are ways to minimise stains caused by coffee, as well as other foods and beverages, you should prioritise good oral hygiene. When you brush your teeth frequently with or without a whitening toothpaste, you will reduce the amount of plaque there and prevent future staining.

How to prevent tea stains on teeth?

A lot of teas contain tannin, which can stain your teeth more than coffee. The deeper the colour of the tea you are drinking, the more it can stain teeth. In order to keep your smile white after drinking tea, try out the following tips:

• Rinse with water/mouthwash after drinking tea - dark-coloured liquid may get stuck and your teeth may darken. That is why rinsing with water or mouthwash can help remove leftover liquid stuck between the teeth.
• Reduce tea intake - if you notice your teeth lose their whiteness after you consume beverages such as coffee and tea, then the simplest thing to do is to reduce or avoid coffee or tea.
• Switch the type of tea - black tea is a major culprit for causing your teeth to look stained. Switching to green, peppermint or white tea can reduce the white spots on your teeth and reduce discolouration.
• Brushing and flossing are a must - you may not be able to prevent discolouration, but at the very least you can keep the outer layer of enamel clean by brushing and flossing regularly. Flossing and brushing your teeth at least twice a day will allow staining to go away. It is also helpful to do it immediately after drinking tea.
• Use a straw - a straw can help prevent the liquid from coming into contact with your teeth.
• Consider some teeth whitening treatment options - you can always make an appointment with your dentist to get your teeth bleached or treated for stains. You can also rely on some over-the-counter products, such as whitening toothpaste or home whitening strips/kits to make your teeth look pristine and white again. There are also LED and Laser bleaching treatments available.

How to prevent food stains on teeth?

Food, even more so than drinks, can cause stains on the surface of your teeth. Foods like curry, pasta sauce, berries and balsamic vinegar can turn teeth dark. Here are a few useful strategies to prevent food stains and white spots on teeth:

• Eat more green vegetables - eating a salad or some dark green vegetables before another staining food provides a layer of protection for your teeth. Eating lettuce along with some of the stain-inducing foods can have a mild abrasive effect, much like using baking soda as part of a DIY method to whiten teeth.
• Cheese helps - hard cheese eaten after an offering of food can neutralise some of the acids that cause food stains and even help strengthen your teeth.
• Drink some water - when you are done with your food, you can drink some water or milk to remove the parts of the food before they set in. You can also rinse your mouth within 30 minutes of eating food to clear some of the stains and not let them set in.
• Brush and floss your teeth - proper tooth brushing and flossing is a great way to reduce stains caused by foods. Brushing teeth soon after eating may not always be convenient, but it is sure to remove food particles before they have had the chance to cause any stains. 

In conclusion, tooth discolouration can be caused by a variety of factors including certain beverages, pigmented foods, medications, and the natural ageing process. There are three types of tooth stains, extrinsic, intrinsic, and age-related stains.

To prevent stains caused by coffee and tea, it is recommended to use a straw, add a little cream, brush or rinse your teeth afterwards, use whitening products, and maintain good oral hygiene. A professional in-office whitening treatment by a dentist can also remove tough stains that penetrate the enamel. Overall, it is important to take preventative measures to maintain a pearly white smile.

So, you just got home from an in-office bleaching procedure, now what? How do you keep your teeth white for as long as possible? It probably won't be a surprise to you that it is in your best interest to follow strictly the aftercare tips provided by your dental professional. But in case they missed something, this post will give you guidance on what to avoid eating and drinking in the days following your teeth whitening treatment. You will also learn how to care for your smile if it gets sensitive after whitening. Let’s go.

Key Takeaways on What to Eat and Drink after Teeth Whitening

• When deciding what food and beverages to have after your teeth whitening session, you should be guided by the colour and substances that are responsible for staining your teeth
• It’s generally agreed that you should follow the "white diet" for a few days
• Smoking is strongly discouraged
• You can go back to eating normally a few days after you completed your teeth whitening procedure

What Foods Can You Eat After Teeth Whitening?

After you have your teeth professionally whitened, the basic principle that will guide you is colour. The lighter the food is, the bigger the likelihood of it being a good choice for you. A great rule of thumb here is: if it can stain a white shirt, then you shouldn't have it. Here is more on the subject.

What can you eat after teeth whitening?

1. Dairy products such as cheese, milk, yoghurt, and cottage cheese
2. White rice and pasta
3. Cauliflower, potatoes, apples, coconuts, white beans, cashews, sesame seeds
4. Poultry and chicken
5. Garlic, onions, pine nuts, bananas, mushrooms, egg whites, and pears

When you ask around about foods you are allowed to have after teeth whitening, you will hear the term “white diet" a lot. As explicit as it sounds, this diet has you eat foods that are white or light in colour. Anything other than that can stain the teeth.

The first things that come to mind are dairy products like cheese, milk, yoghurt, cottage, cheese, etc. Other mentions include white rice, pasta, and anything doughy that doesn’t have added colourants.

Then, we should also add cauliflower, potatoes, apples, coconuts, white beans, cashews, sesame seeds, poultry and chicken, garlic, onions, pine nuts, bananas, mushrooms, egg whites, and pears to the list of permitted foods.

For the first 72 hours, avoid acidic foods and forgo abrasive foods at all costs.

What can you eat after zoom teeth whitening?

Adding a special light to teeth whitening is a common thing to do. It shatters the whitening gel, breaking down any stains faster than normal. Other than that, zoom whitening doesn’t differ much from bleaching because it uses hydrogen peroxide or carbamide peroxide with the same concentration as its alternative.

Hence, the foods and drinks that you can and can’t eat are pretty much the same.

Consider white cheese and yoghurt, white bread, rice, pasta, tofu, chicken, fish, certain fruits and veggies, as well as water as your go-tos after the treatment. Water increases your saliva production, which helps clean the teeth after you consume acidic foods. So, its importance should not be underestimated.

What Foods to Avoid after Teeth Whitening Treatment? Which Foods and Drinks Easily Stain Your Teeth?

• Dark-coloured foods and liquids: black rice, chia, black seed oil, black beans, black garlic, etc.
• Foods that have natural colouring: red meat, chocolate, ketchup, tomatoes, spinach, strawberries, radishes, beets, matcha, cherries, raspberries, blueberries, red cabbage, turmeric, saffron, paprika, sweet potato, purple sweet potato, carrots, pomegranates, etc.
• Acidic beverages: alcohol, fruit juices, soft drinks.
• Other things to avoid consuming: curry, tomato-based sauces, soy sauce, balsamic vinegar, and sugary foods like ice cream, cookies, cakes, etc. (stick to white sauces instead if you can't do without any sauce at all).
• Drinks that are absolutely out of the question include coffee, hot chocolate, fruit juices, tea, red wine, and cola.

Can I Drink Alcohol After Teeth Whitening? What Habits to Avoid After You Whiten Your Teeth?

Basically, no. For the most part, it is a good idea to avoid alcohol in all its forms but if you really can’t help yourself, we recommend sticking with clear liquids such as vodka, gin, and white wine. Avoid fuzzy drinks and coloured drinks such as beer, red wine, tea and any juices.

Can I Brush My Teeth After Whitening?

Of course. You should do your best to keep your teeth clean at all times so that food doesn’t get the chance to stain them. At the very least, brush and floss like you normally would and don’t let food deposits sit for too long on your pearly whites.

Please note that these tips apply to both professional teeth whitening services and over-the-counter whitening with whitening strips and trays. For any questions regarding your white smile, contact your dentist.

How to Reduce Teeth Sensitivity after Whitening and Brushing Your Teeth

As dental whitening bleaches stains on your teeth, it can make the structures sensitive to hot and cold. The tooth enamel temporarily becomes more permeable, which leaves the dentin underneath unprotected.

One of the tips you’ll get from your dentist is to switch to a special toothpaste for sensitive teeth after your treatment. You can also use desensitizing gels. These are designed to block pain signals from the tooth structures to the nearby nerves.

When it comes to beverages, it is advised that you drink through a straw to minimize contact with your teeth. If you have a sensitive tummy or suffer from bloating, this may not be a good idea, so give it a thought before you do it. It’s best to avoid anything acid-based, as well as cold and hot drinks because they can cause pain at this point.

If you have a lingering sensitivity, you might want to take ibuprofen or any other pain medication that works for you. Don’t go overboard with it, though.

Also, when brushing your teeth, be gentle and use a soft-bristled brush. Go with lukewarm water. Do not brush your teeth right after meals but wait for 30 minutes before you do so.

Last but not least, do not smoke. Not only will tobacco products stain the teeth undoing the results you got from the whitening session, but they can cause sensitivity issues. Plus, they aren't good for your oral health anyway.

Be sure to follow any tips your dentist provided and you will be fine. If you still experience tooth sensitivity greater than what you expected, get in touch with the specialist to vocalise your issues and get help. Whiter teeth shouldn't cause that big of an issue.

Final Thoughts on Teeth Whitening Aftercare, White Diet and What to Avoid Drinking for a White Smile

Without a doubt, you should be extra careful about what you eat for the first few days and hours after teeth whitening. This way, you will avoid staining your teeth and maintain the pearly white colour of your teeth for as long as possible. The bottom line is, you should avoid fruits with acids and those that cause staining like berries, pomegranates, and cherries. Drinks that can compromise the colour of your teeth include the likes of wine, coffee, tea and fruit juices.

Avoid foods that have artificial colouring or natural colouring such as beetroots, spinach, tomato-based sauces, etc. If you follow these rules, your teeth will remain white for a long time.

If you cannot commit to a diet for a while, you should reconsider getting your teeth whitened as that would significantly decrease the effectiveness of the treatment.

What you need to know about LED teeth whitening in Singapore

When it comes to dental care, teeth whitening is one of the most common treatments that individuals choose to go with. It goes a long way to providing you with many shades of a brighter smile, which can complement your brushing and flossing. There are numerous whitening treatments available. From sessions performed in your dentist's office, to various products like whitening strips, you can use at home, the options are plenty.

One way you can improve the whiteness of your teeth by at least 8 shades in a single session is the LED light method. It is an increasingly popular method, which uses LED technology to whiten the surface of the teeth. It is non-invasive and a dentist can perform it in a quick session to provide you with a whiter smile. The following guide will give you more information on this whitening system.

How does LED teeth whitening work?

In order to deal with stains in the most efficient manner possible, the led light method has been developed. This teeth whitening treatment is one you can do at your dentist's office for a quick result. It is not just the use of LED light involved in the process. There are a few more important steps that take place before the light is even introduced:

• The dentist will clean the surface of your teeth. This ensures the whitening agent they are going to apply next covers the enamel evenly.
• Next up, they apply a whitening gel on your teeth as evenly as possible. They may use special tools to keep your mouth open and thus protect the soft tissue there. The whitening gel needs to sit for about 20 minutes.
• Then, an LED light is introduced. The LED light will activate the whitening gel speeding up the reactions that remove stains from the teeth.

Teeth are porous and they absorb liquids and food. That is the reason why there are sometimes stains on the enamel of your teeth after drinking tea, red wine or coffee. The pores also absorb the whitening gel applied during the procedure. It contains an active ingredient of hydrogen peroxide. This is the same ingredient found in other over the counter whitening products, though its concentration may vary.

When hydrogen peroxide gets in contact with teeth, it serves as a catalyst for an oxidation reaction. It breaks down the bonds between discoloured molecules, causing the stains to disappear. And while the whitening session lasts only a limited time, the effect persists for about 24 hours afterwards.

Does LED teeth whitening work?

When you expose a light-emitting diode to electricity, it releases a single colour of light on the visible light spectrum. In the past, UV light was used, but that was found to have the risk of causing cell mutation and so it has been replaced by LED. It only needs minimal power and it really speeds up the chemical reactions that the whitening gel creates on the layer of dentin. The light is intense, but it is also cooler because it dissipates heat. As mentioned before, the effect of a whitening gel is ongoing for about 24 hours after use. So the more intense the reaction is for the time it sits on the teeth, the more effective it can remove stains. This is how LED light teeth whitening works in many dental aesthetic clinics.

Is LED teeth whitening safe - does LED whitening damage your teeth?

Like many teeth whitening procedures, LED teeth whitening can lead to tooth sensitivity and mild discomfort due to gum irritation in some people. You should factor this in, especially if you have sensitive teeth. The procedure is safe and any side effects are quick to disperse. But to be 100% safe, you should still consult with your dentist about a suitable solution for whitening teeth. Perhaps they can recommend non-peroxide and non-bleach options, such as using whitening toothpaste as a substitute for more powerful aesthetic treatments.

LED vs laser teeth whitening

Laser whitening shares some characteristics with LED whitening. It starts with a thorough cleaning of plaque, filling in cavities, etc. The dentist then fits in a mouth tray with whitening gel over the teeth, along with a plastic dam over the gums, to keep them safe. Then they will use a laser to activate the whitening gel with a concentration of hydrogen peroxide anywhere between 10 and 35%. The goal is to have the whitening agent do its job fast so that it doesn't stay in contact with the teeth for prolonged periods of time. This method is great for heavy stains. For example, if the person has been smoking and chewing tobacco for a long period of time, a dentist may recommend laser whitening.

Using LED light follows the same principle, only that it takes a bit longer due to the light not having any heating properties. The whitening agent itself contains less hydrogen peroxide - about 6% concentration. Because LED light is safer than a laser, there is less chance for any side effects to occur.

Those who have tried the LED whitening method report that it works great, even if it takes a little longer than using a laser.

LED teeth whitening pros and cons

There are numerous pros to LED teeth whitening:

• It is very fast - sessions take around 20 minutes
• It is not harmful to teeth enamel or structure of the teeth
• It is a modern method developed through the use of technology
• It doesn't transmit heat to the tooth and doesn't cause discomfort

Some potential cons:

• Slight discomfort is possible during the procedure
• Some teeth sensitivity is to be expected due to the bleaching agent

LED teeth whitening Side Effects and Risks

Some individuals report increased tooth sensitivity after LED whitening, which is normal. Every time teeth are exposed to a whitening agent, there can be some sensitivity. But because LED whitening usually relies on a gel that contains a smaller concentration of hydrogen peroxide, this side effect is not as pronounced as other methods. Even if it does appear, it should go away soon after. Mild irritation of the gums is also likely, but nothing too severe should come out of it.

To lighten the surface of your teeth properly using the LED method, you should always look to do so in a dental office. Your dental care provider will know how to follow the procedure in the best way possible. From the application of the whitening agent so that it can penetrate teeth stains to using the right tools for the job, they will minimise the risks for you and ensure good results. Side effects are less likely then. Obviously, if you want to repeat the process several times, there is a higher risk that some of these side effects will appear.

Frequently Asked Questions About LED Teeth Whitening

There are several factors involved in developing teeth stains. Nicotine from smoking is one of the leading causes of tooth discolouration. Nicotine is in fact colourless, but it turns yellow once it comes in contact with oxygen. Combined with the fact that teeth have tiny pores, which absorb the nicotine from smoking, it is clear how this bad habit can lead to long-term stains.

Thankfully, dental offices, good oral hygiene and some over-the-counter products provide an efficient solution to surface stains. Whitening treatments and methods to combat teeth stains from smoking can aid those that find quitting smoking to be very difficult.

What are some DIY methods for teeth whitening?

If you are not dealing with severe discolouration and want to try some DIY at-home treatments first, there are a few options you can look into:

Brushing with baking soda and peroxide solution

One of the most recommended methods for dealing with teeth stains is mixing a single tablespoon of baking soda with a few drops of hydrogen peroxide. Together they create a paste-like solution you can brush your teeth with. Baking soda is a mild abrasive, which helps oxidize stains and remove them when mixed with peroxide. It is recommended to only use this solution 2-3 times a week, to prevent the enamel from breaking down.

Using natural whiteners

There are a few natural whiteners that can help you remove stains:

• Orange peel scrub - the acidic content has two major uses. On one hand, it acts as an antimicrobial agent. On the other hand, the content of citrus fruits can help the whitening effect. Rub the inside part of an orange peel on your teeth, then rinse and continue with your regular cleaning method.
• Strawberries - the ascorbic and malic acid in strawberries can lighten stains. Mash a single strawberry with a teaspoon of baking soda. Gently rub the mixture onto your teeth, let it sit for a few minutes and then rinse it off.
• Guava leaf paste - to minimise oxidative stress from various microorganisms that cause teeth stains, you can use guava leaf paste. It is rich in flavonoids and phenols and can be made from just 1-2 crushed guava leaves. Rub the resulting paste on your teeth, then rinse it off and wash it with regular toothpaste.
• Apple cider vinegar infused with some lemon - dip your toothbrush in a mix of 2 tablespoons apple cider vinegar and 1/4 lemon juice. Rinse well afterwards and make sure you don't use this method too often because it can be harmful to your enamel.

Oil pulling

Oil pulling is an old Indian remedy that involves swishing oil around your mouth to get rid of bacteria. Coconut oil is the most popular choice for this teeth whitening method. It can completely remove and dissolve bacteria in the mouth, improving the hygiene of the mouth. It helps against gum disease, gingivitis and bad breath. And because it removes bacteria, it is also a good option for removing stains from your teeth.

Use over-the-counter teeth whitening products

If you are looking for a simple solution to stains, over-the-counter whitening toothpaste can be a good choice. With their mild abrasive effect, such kinds of toothpaste are ideal for scratching stains off the surface of the teeth. However, they also pose a risk, because using them more often can wear out the enamel on your teeth. An at-home whitening gel and whitening strips are other options you can ask your dentist about.

Professional teeth whitening options

If you feel like the DIY methods don't cut it, you can look into getting professional services. Here is what your dentist can help with.

Regular dental cleanings

One of the best ways to deal with the outcome of chewing tobacco is to have a teeth whitening procedure with your dentist. The purpose of a dental cleaning is to remove both surface stains and tartar buildup from your teeth. Since tobacco smoke deeply stains your teeth, it is important to have a professional check out the best resolution. The procedure usually involves having your teeth painted in peroxide solution. They are then exposed to strong light for a very thorough cleaning.

One more reason to rely on your dental professional to keep your teeth white is they will also do an exam. This can be very important if you have gum disease, tooth sensitivity or gum damage. The expert will assess the situation and recommend the best course of action for your case with minimal risk. A well-performed in-office teeth whitening procedure can provide results for up to three years.

Have a custom tray fit

With this option, you will have your dentist design a custom tray fit to the exact dimensions of your mouth. With it, you can carry out whitening procedures at home by having the product in your mouth for a certain amount of time.

Dental bleaching

You can have your dentist provide you with a customer whitening tray or perform in-office bleaching to have your teeth look sparkling white. This is usually done with a whitening gel that can completely eliminate the way nicotine affects your teeth. Such gels usually contain carbamide peroxide and hydrogen peroxide, which are very strong and used in teeth whitening techniques.

How to best prevent stains on tooth enamel?

Here are 5 steps to follow to be proactive in preventing stains on your teeth.

1. Stop smoking

You are well aware of the negative impact of smoking on your overall health and immune system. You should work on setting the goal to quit smoking if possible. As a smoker, you can expect nicotine stains to disappear once you have stopped the habit. Moreover, it will improve your oral health, even if you have been a smoker for a long time.

2. Brushing and flossing

If you are a smoker, the next best thing to quitting is to be proactive and maintain good oral hygiene. In other words, brush or floss your teeth after smoking to remove the thin layer of tar and chemicals causing stains.

3. Try anti-tar mouthwash

This is a product made for people who smoke a lot. Using it before you brush your teeth with specialised toothpaste is a good way to prevent stains and keep your teeth light.

4. Make alterations to your diet

Apples, carrots and celery are all great foods that remove stains. Being rich in Vitamin C also makes them ideal for the prevention of dental diseases. Citrus fruits (orange, pineapple) contribute to generating additional saliva to wash and whiten teeth. For enamel preservation, make sure you include dairy products in your diet. They also nourish the gums and jaw muscles. Read more about maintaining white teeth with our diet and aftercare tips.

5. Go for regular dental checkups

By paying your dental professional a visit, you can not only deal with stains but make sure your teeth are in good overall condition. Your dentist knows best how to address issues with your teeth and offers the most risk-free approach to whitening and dealing with problems. That is why smokers generally rely on professionals for their dental care.

What is teeth whitening?

Teeth whitening is a treatment which can remove stains and make your teeth appear whiter. In general, there are various options to achieve that. One of the quickest and most effective ways is to get professional teeth whitening. All you need to do is to make an appointment with your local dentist. The procedure involves the application of a bleaching agent (hydrogen peroxide or carbamide peroxide) and then activating it with light or a laser. When these powerful materials penetrate the tooth enamel and dentin layers, they break down staining molecules, giving you a whiter smile.

Another option to brighten your teeth is to get an at-home whitening kit from your dentist. The packet usually includes custom-made whitening trays and a bleaching agent (gel). Your dental provider will give you an instruction on how to use it so that you get the results you want. Alternatively, you may purchase OTC teeth whitening products and conduct the treatment at home. Such items are cheaper than professional procedures. They can, however, usually only address minor discoloration and cannot remove tough stains.

What are veneers?

Dental veneers are restorations that are placed on natural teeth. They are custom-made devices which fully cover the front part of the tooth's surface. Veneers are a great option if you want to change things about your smile that you couldn't address otherwise, specifically colour, shape, size, and chipped teeth. These thin shells can be made from either porcelain, ceramic or composite material, depending on your needs and preferences.

The dental veneer procedure typically requires two appointments at the dentist. On your first appointment, the dental professional will make space for the shells by removing a thin layer of your tooth enamel. To provide you with veneers that perfectly fit your teeth, the doctor will also take a dental impression or maybe an oral scan. This will be sent to a dental laboratory for manufacture. You will get your permanent veneers on your second visit. Meanwhile, your dentist may cover your teeth with temporary veneers.

Teeth whitening vs veneers: Pros and cons

Both, teeth whitening and dental veneers can help you improve your smile. They are highly effective and can give you beautiful, white teeth. However, these two treatments can accomplish this in different ways. Each of them comes with its advantages and disadvantages.

Pros and cons of professional teeth whitening

Here are some of the advantages of teeth whitening procedures.

• They can reduce yellowing and discolouration caused by certain foods, drinks, and tobacco use.
• Professional teeth whitening is a very quick and easy treatment, completed in about an hour. In addition, the results are visible immediately.
• The procedure is completely non-invasive and painless. All you need to do after having your teeth whitened is to avoid staining foods and drinks for about 2-3 days.
• Teeth whitening is a much less expensive smile makeover option than veneers.

The downsides of the teeth whitening treatments include:

• Some people may experience increased tooth sensitivity for a few days following the whitening session.
• Although teeth whitening treatments can significantly eliminate discolouration, they might be not able to fix issues such as broken teeth or gaps.
• Teeth whitening procedures are not a permanent solution. If you get in-office treatment, then your results may last for about 2-3 years. However, if you overdo with staining drinks and foods, then your pearly whites may turn yellow as soon as 6 months.

Pros and cons of dental veneers

Here we will list some of the benefits of dental veneers.

• In addition to providing a brighter smile, veneers can also be used to correct other oral health issues. They can fill spaces, and cover teeth that are stained, poorly shaped or crooked.
• Veneers are usually a permanent treatment option. They are typically bonded to the front part of visible teeth with special cement. With proper oral hygiene habits and care, they may last over 20 years.
• If you opt for porcelain veneers, you will not have to worry about tooth discoloration, since the material is stain-resistant.
• The shells are very durable and provide very natural-looking results.

Veneers also come with some downsides which you may want to consider.

• The procedure is minimally invasive. However, your dental professional will use a numbing agent, so you don't feel any discomfort or pain.
• The placement of veneers is normally done in multiple appointments. In most cases, it requires two dental visits.
• Veneers are quite costly when compared with teeth whitening. Porcelain shells tend to be the most expensive type of veneer.

Teeth whitening vs veneers: which is better for you?

What option is right for you? It really depends on your needs and cosmetic goals. There are a few key factors that you may want to consider when choosing the best treatment for you. The first thing you should think about is the condition of your teeth. If you only have discolouration from certain foods and drinks, teeth whitening may help you get rid of it. If you have deep-set staining and uneven spacing, then veneers can be the better choice.

The second thing to consider is how long you are willing to devote to treatment. In-office teeth whitening is a single-time treatment that is painless and has no serious side effects. It can change the appearance of your smile quickly. However, the results are only temporary, lasting between 1-2 years. Veneers, on the other hand, require two dental visits to be placed, but they are a more permanent solution.

The third important factor to consider is the price. Veneers are a great option if you want to completely transform the look of your pearly whites. However, this comes at a higher cost. Composite veneers, for example, may cost you about S$200-300 per tooth, whereas porcelain veneers cost up to S$1500 per tooth. Teeth whitening treatments are much more affordable, costing around S$900-1200 per session.

If you are not sure whether teeth whitening or a veneer procedure is better for you, consult a professional who is experienced in either cosmetic dentistry or general dentistry.

Frequently asked questions

Tooth whitening can give you a better smile in a relatively short period of time. Many patients want to know whether they can get their crowns, veneers, or implants whitened because they have started to develop stains and discolouration in certain areas. The truth of the matter is, while you can whiten your teeth, you can’t bleach dental restorations.  Here is more on the topic.

Key Takeaways of Ceramic Teeth Whitening

• Teeth whitening with implants, crowns, dentures, and veneers is possible but the tooth restorations themselves cannot be bleached if they develop stains
• When making your decision to whiten your teeth, you should consider the risk of your teeth becoming whiter than your prosthetics
• Before you proceed to whiten your teeth, please talk to someone who specialises in cosmetic dentistry, especially if you have crowns or veneers
• Brown lines in the area where the tooth meets porcelain veneers might be a sign of receding gum line

Can I Whiten Ceramic Teeth Like Dental Implant?

The short answer is, dental implants cannot be bleached. Since it’s easier to match the colour of the dental prosthetics to the natural teeth, not vice versa, dental implants are typically set in a shade that’s closest to your natural tooth colour. This means that you don’t need to bleach them.

Be that as it may, your teeth may turn yellow over time compromising the results you previously achieved. If your natural teeth have changed in colour and you want your implant to make a perfect match, you can replace the dental crown with one that is the same colour as your teeth. Although that’s going to take an extra trip to the dentist and cost you some money, it is still an acceptable solution.

Yet, a much better option would be to schedule a tooth whitening session with your dentist for a more confident smile. The bleaching agent will not affect the dental material in any way, so it’s perfectly okay to have the procedure. However, there is one thing to keep in mind: you need to match the colour of the implants. Otherwise, it will be obvious that they are artificial.

Can I Whiten Crowns?

A dental crown is generally made of the same materials as the top layer of implants, so similar rules apply here. It cannot be whitened but it won’t be an obstacle if you choose to whiten your natural teeth.

Before you do that, you should weigh down the pros and cons of this plan of action. If the dental crowns are positioned at the back of your teeth, they won’t be as visible, which means you don’t need to have them replaced. If they are close to the front surface of your teeth, that's a different story. All in all, before you get crowns, you need to have a conversation with your dentist about their effects on your smile and appearance.

Can I Whiten Veneers?

Once they are placed in your mouth, dental veneers cannot be whitened. The same applies to all kinds of bonding materials, as mentioned earlier. Whitening products are used only on natural teeth, not on veneers. Thus, if they darken, they will have to be replaced with new ones that fit the current shade of your teeth.

It is important to differentiate the two types of materials that veneers are usually made of. Composite veneers tend to grow stains over time as a result of exposure to certain foods and bad habits like smoking. They may not stain as easily as your natural tooth enamel, but they are still going to get there someday. Now, veneers made of porcelain will maintain the same shade and are not affected by the foods or drinks you consume. It’s all a matter of porosity.

If you want to do a combination of both procedures, it is recommended that you have traditional whitening treatments booked first before you move on to your veneer appointment. This way, you will enjoy a beautiful smile that looks natural and is free of imperfections. All things considered, you should look for dental professionals who can take good care of your smile and provide you with a treatment strictly adapted to your needs.

We often get asked if people should get veneers instead of whitening their teeth. To answer that, we've written a dedicated article comparing teeth whitening vs veneers.

What’s the Deal with Porcelain Veneers?

Without a doubt, porcelain veneers are at an advantage because they are highly resistant to staining. But because you will probably have them for many years, this may turn out to be a problem. The reason is simple. Your teeth may change in colour over time contrasting directly with the dental prosthetics. This will put an emphasis on some parts of your mouth, making it pretty obvious that you are using artificial materials.

A similar thing can happen if you choose to use teeth whitening products after you place your veneers. Your teeth will become a few shades brighter than your veneers. This will compromise your smile.

What Other Issues Can There be with Veneers?

While porcelain veneers aren’t prone to staining, some patients get small brown lines alongside the site at which the tooth meets the veneers. This might indicate a gum recession. In that case, you should consult your dentist to see what steps can be taken to slow down the process.
