Teeth whitening is a famous cosmetic dental treatment because it can enhance your smile by making your teeth several shades whiter. But similar to other dental services, teeth whitening also comes with risks. Fortunately, these side effects are usually mild and can include tooth sensitivity and gum irritation. Before getting your teeth whitened, you must talk to your dentist about the potential risks and side effects. Read on to find out more so you can make an informed decision. What Is Professional Tooth Whitening?This dental treatment is a safe and effective way to lighten the colour of your teeth. It involves using bleaching agents, such as hydrogen peroxide or carbamide peroxide, to remove stains and discolouration from your tooth’s surface. This procedure can restore the natural colour of your tooth or even make it several shades lighter. Depending on the person, its effects can last up to 2 to 3 years, or as less as six months. There are reasons why your teeth can become discoloured or stained over time. These include:
You have to note, though, that there are two main types of tooth whitening: in-office and at-home. A dentist does professional in-office teeth whitening in a dental clinic, which usually takes an hour or less and requires only one session. On the other hand, at-home teeth whitening is a do-it-yourself method that uses a bleaching kit. It involves wearing a mouthguard-like tray filled with a bleaching gel for a certain period (typically 30 minutes to an hour) on a daily or nightly basis until you achieve the desired results, often up to 2 weeks. You can purchase this whitening product from a dentist or over the counter. How Does Teeth Whitening Work?![]() The bleaching agents used in tooth whitening work by breaking down into oxygen molecules. These oxygen molecules then penetrate your tooth enamel and break up the stains and discolouration, making them appear brighter and whiter. Two types of bleaching agents can be utilised in this procedure, including:
What Are the Risks of Tooth Whitening Treatment?![]() This procedure is generally considered safe. However, as with any dental treatment, you should be aware of potential risks and side effects before whitening your teeth. These include: 1. Tooth SensitivityThis usually happens when the bleaching agents penetrate too deeply into your tooth enamel, causing the dentin to become exposed. Dentin is your tooth’s layer that’s softer and more porous than enamel. It helps support the tooth’s structure and protects its pulp, which contains nerves and blood vessels. When your dentin becomes exposed, it can make your teeth feel sensitive to hot and cold temperatures and sugary and acidic. This sensitivity is often temporary and should go away once the bleaching agents are removed from your teeth. If you suffer from tooth sensitivity after the treatment, try using toothpaste for sensitive teeth or rinsing your mouth with a fluoride mouthwash. You can also consider taking over-the-counter pain relievers, such as ibuprofen or acetaminophen, to help relieve any discomfort. Talk to your dentist if your tooth sensitivity persists. 2. Gum IrritationGum irritation can happen when the bleaching agents come into contact with your gums. It can make your gums become red, swollen and sore. It usually resolves on its own after one to a few days, but you may try mouth rinsing with salt water or using a topical numbing gel to help relieve any discomfort. If you have gum disease, you tend to be more prone to gum irritation after getting your teeth whitened. That’s because the bleaching agents can irritate and inflame your gums. 3. Over WhiteningThis usually occurs in home-based treated teeth, as patients tend to overuse the whitening agents in an effort to achieve faster results. Over whitening your teeth can cause them to become translucent, making the yellowish colour of your dentin more visible. It can also make your teeth look blue or grey. To avoid this occurrence, talk to your dentist about how often you should whiten your teeth and what concentration of bleaching agent is right for you. Your dentist can also help you determine how long you should leave the bleaching agent on your teeth. 4. Burns and BlistersIn rare cases, the bleaching agents used in teeth whitening can cause burns or blisters on your gums. This usually happens when the gel used is left on your teeth for too long or if it’s not applied correctly. If you suffer from these burns or blisters on your gums after getting your teeth whitened, you may rinse your mouth with cold water and apply a topical numbing gel. If the pain persists, see your dentist. 5. Allergic ReactionsIn some instances, you may also have an allergic reaction to the bleaching agents used in teeth whitening. This can cause symptoms like:
Visit your dentist or doctor right away if you experience any of these symptoms after getting your teeth whitened. 6. Upset StomachIn another rare case, teeth whitening can cause an upset stomach. This usually happens when you swallow the bleaching agents used in the procedure. If you have an upset stomach after whitening your tooth, try drinking plenty of fluids and eating bland. 7. Rough TeethUnfortunately, this treatment may make your teeth feel rough, as well. This usually occurs when the bleaching agents used in the procedure are left on the teeth for too long. If your teeth feel rough after getting them whitened, try using toothpaste for sensitive teeth or rinsing your mouth with a fluoride mouthwash. You can also consider taking over-the-counter pain relievers, such as ibuprofen or acetaminophen, to help relieve any discomfort. Talk to your dentist if it persists. Is Tooth Whitening Safe?While there are several risks associated with teeth whitening, the procedure is generally safe when done by a professional. They are trained and certified and know how to apply the bleaching agents properly and how long to leave them on your teeth. If you have gum problems and are considering getting your teeth whitened, discuss it with your dentist first to know if it’s safe for you. Can I Get a Tooth Whitening Treatment if I Have Gum Disease?There are various kinds of gum diseases, such as gingivitis and periodontitis. Gingivitis is a mild form of gum disease that can be reversed with proper dental hygiene. However, periodontitis is a more severe form that can damage the gums and the bones that support the teeth. If you have any gum conditions, you may want to avoid whitening your teeth. This is because the bleaching agents used in the procedure can irritate your gums and make the problem worse. Consider addressing your gum issue first before getting your tooth whitened, or inform your dentist so that they can plan what’s best for your condition. ![]() Who is a Good Candidate for Tooth Whitening?People who have healthy gums and teeth are good candidates for this dental treatment. However, certain conditions may make you ineligible for the procedure. These include:
During your dental visit, your dentist will tell you if you have any of these conditions and give you professional advice on what to do next. What Are the Advantages of Getting Your Teeth Professionally Whitened?There are a number of benefits of getting your teeth professionally whitened, such as:

Are There Alternatives to Teeth Whitening?If you’re not a candidate for tooth whitening or you’re looking for an alternative, there are a few options available, such as: Dental VeneersThese are thin pieces of porcelain installed over your tooth’s front surface. They can be used to improve the appearance of your teeth and make them look whiter by hiding any staining or discolouration. Dental BondingThis is a procedure wherein your dentist applies a tooth-coloured resin to the surface of your teeth and then hardens with a UV light. This can help improve your teeth’s appearance and make them look whiter. CrownsCrowns are especially beneficial for both restorative and cosmetic purposes. They can be used to cover up discoloured teeth, protect a weakened tooth from further damage, or support a tooth that has been damaged. The treatment involves taking an impression of your teeth and sending it to a laboratory where the crowns will be made. These are then placed over the entire surface of your teeth, covering them completely. Final ThoughtsIn general, teeth whitening is a safe and effective way to improve the appearance of your tooth, giving you a brighter smile. While some risks are involved, these can be avoided if the treatment is performed by a dental professional. The most common teeth whitening side effect is tooth sensitivity. This often subsides within a few days to a week after treatment. Other potential side effects include gum irritation, redness, and soreness in the mouth. These side effects are also typically temporary and will resolve on their own.
