Whether you are using disposable whitening trays or custom trays with the whitening gel added to them, they are generally worn from 15 minutes to one hour per day for anywhere from five to 10 days.

Whitening gels contain an active whitening ingredient, either carbamide peroxide or hydrogen peroxide.  Peroxide gels break down into water, oxygen and reactive oxygen molecules.  These reactive oxygen molecules treat both the enamel and the dentin, oxidizing the bonds of discolored stain molecules.  By changing the stained molecules, the tooth becomes lighter.

Tooth or gum sensitivity can occur as a result of whitening.  If sensitivity occurs, it is temporary and typically disappears within a day or two.  Over the counter desensitizing products can be used to help treat sensitivity.

Sensitivity during the treatment may occur with some patients.  On rare occasions, minor tingling sensations are experienced immediately after use, but always dissipate. You can also ask your dentist to supply you with anti-sensitivity toothpaste for use prior to treatment.

More people than you might imagine. A bright sparkling smile can make a big difference for everyone. A little investment can go a long way.

Almost anyone. However, treatment may not be as effective for some as it is for others. Your dental professional can determine if you are a viable candidate for this procedure through a thorough oral exam.

Whitening your teeth has not been shown to weaken tooth enamel or cause gum recession.
