Teeth whitening performed under the supervision of a dentist is one of the most effective ways to improve the color and brightness of your smile. While it has become very popular, many people are unaware of the potential risks and limitations of whitening treatments. Not everyone’s teeth are suitable for whitening, and if your teeth or gums are not healthy, the procedure may cause more harm than good.
The safest way to find out if teeth whitening is right for you is to schedule a consultation with Dr. Kaufman. During your appointment, we will check important factors such as enamel thickness, gum health, existing restorations like fillings, crowns, and veneers). We also examine the cause of discoloration—whether it comes from diet, ageing, medications, or internal factors.
While teeth with surface stains may respond well to whitening, deeper internal discoloration might require different treatment options.
How Teeth Whitening Works
Professional teeth whitening uses oxidising agents such as hydrogen peroxide to alter how the tooth surface reflects light. Used correctly, this process safely brightens the enamel. However, repeated or improper use over long periods can cause irreversible damage to teeth.
There are two main whitening methods:
-
Take‑home whitening trays: Custom trays made by your dentist for controlled use over 1–2 weeks.
-
In‑chair whitening: A dentist applies the whitening gel in one or two visits, sometimes using light or heat to accelerate the results.
What to Expect During and After Treatment
Some patients experience a mild “bubbly” sensation or slight tooth discomfort during the application. Temporary sensitivity may occur after treatment, especially when biting. These effects typically subside within a few days. If sensitivity persists, please contact us.
How to Maintain Whiter Teeth
To keep your smile bright for longer, reduce daily staining from foods and drinks. Stains can come from plaque, tannins, tobacco, and colored foods. Common sources of staining include:
-
Herbal or black tea
-
Coffee
-
Red wine
-
Spicy foods such as curries
Smoking also causes persistent surface stains that are difficult to remove. For best results, any visible stains should be cleaned professionally before whitening. To get started, schedule an appointment with us today and restore the natural brightness of your smile.
