Professional teeth whitening has become an increasingly popular dental treatment for those looking to brighten their smile and remove stains caused by factors such as coffee, smoking, or ageing. Many people opt for professional teeth whitening because it offers quick results, is relatively safe when performed by a trained dentist, and provides a more noticeable effect than over-the-counter treatments. However, like any cosmetic procedure, it is important to be aware of the potential side effects of professional teeth whitening before making a decision.
What is Professional Teeth Whitening?
Professional teeth whitening is a dental procedure in which a dentist applies a bleaching agent to the surface of your teeth to lighten their colour. The most common products used are hydrogen peroxide or carbamide peroxide, which work to break down the molecules causing tooth discolouration. Depending on the method used, the procedure can be done in a single visit to the dentist’s office or at home with custom trays provided by the dentist.
While the treatment is generally considered safe, there are certain side effects that some patients may experience, especially if they have sensitive teeth or underlying dental issues.
Common Side Effects of Professional Teeth Whitening
1. Tooth Sensitivity
One of the most common side effects of professional teeth whitening is tooth sensitivity. Many people report feeling a sharp, temporary pain or discomfort in their teeth, especially when consuming hot or cold foods and drinks. This occurs because the bleaching agents used in whitening treatments can temporarily increase the sensitivity of the enamel, exposing the softer dentin layer underneath.
Tooth sensitivity usually lasts for a few hours to a day or two after the procedure and should subside on its own. Your dentist may also offer treatments, such as fluoride varnishes or desensitising toothpaste, to reduce the discomfort.
2. Gum Irritation
Another potential side effect of professional teeth whitening is gum irritation. The bleaching agents used in the whitening process can cause a mild burn or irritation to the gums if they come into contact with them. This can lead to redness, swelling, or even peeling of the gum tissue.
In most cases, gum irritation is temporary and resolves once the treatment is complete. Dentists take great care to apply the whitening solution carefully, but it is still important to follow any aftercare instructions to ensure that the gums heal properly.
3. Uneven Whitening Results
While professional teeth whitening is designed to create uniform results, there are instances where the treatment may not whiten the teeth evenly. For example, if a patient has dental restorations such as crowns, fillings, or veneers, these materials will not bleach in the same way as natural teeth. As a result, the teeth may appear unevenly whitened, with the natural teeth being lighter than the dental work.
Before undergoing professional teeth whitening, it is essential to discuss your options with your dentist. They may recommend alternative treatments for these areas or suggest waiting until you have had dental work replaced before undergoing whitening.
4. Overuse of Teeth Whitening Products
Although this is not a direct side effect of the professional whitening treatment itself, overusing teeth whitening products can lead to damage to the enamel. Over-the-counter whitening products, such as toothpaste or strips, can cause the enamel to erode if used excessively, leading to long-term sensitivity and discolouration.
It is essential to only undergo professional teeth whitening under the supervision of a qualified dentist to ensure that the procedure is performed safely and effectively. Dentists will ensure that the treatment is tailored to your specific needs and that your teeth are not subjected to excessive whitening.
How Much Does Professional Teeth Whitening Cost?
The professional teeth whitening cost can vary significantly depending on the type of treatment, the dentist’s location, and the condition of your teeth. In Australia, the average cost of professional teeth whitening typically ranges from $500 to $1,000. Some dental clinics may offer promotional deals or payment plans, making them more affordable for patients.
While the teeth whitening cost may seem high compared to over-the-counter products, the results are often more dramatic and long-lasting. Professional whitening also ensures the safety and health of your teeth and gums, which is not guaranteed with over-the-counter treatments.
In summary, professional teeth whitening is an effective and safe way to enhance the appearance of your smile, but like any cosmetic procedure, it does come with some potential side effects. Tooth sensitivity, gum irritation, uneven whitening, and the risk of overusing products are all possible outcomes. However, these side effects are typically temporary and manageable with proper aftercare. Before deciding to undergo professional teeth whitening, it is crucial to consult with your dentist to ensure that your teeth are suitable for whitening and that you are aware of any potential risks. While the cost of teeth whitening may seem high, the benefits of having a brighter, more confident smile may well be worth it. Always follow your dentist’s advice for the best and safest results.
