Tooth Whitening

1. Is tooth whitening effective?

Yes it is effective for 95% of the population, though there is a 5-10% possibility that it will not be effective for some, especially for those who have intrinsic stains.

2. Is tooth whitening safe?

Yes, as long as you use the right amount as instructed by your dentist. A common reaction to whitening material is sensitivity, thus there is a need to use potassium nitrate after bleaching. Other possible reactions are sore throat and gum irritation.

3. Is tooth whitening permanent? How long does it usually last?

While you may achieve very satisfactory results with tooth whitening, it is not permanent. The dentist advises that you need a regular check up for prophylaxis and a “touch up” of tooth whitening material every 6 months to maintain your desired shade. It is best to avoid heavily colored foods such as red wine, grapes, coffee and tea and also smoking since these contribute to staining.

4. How long does it take for results to happen in tooth whitening?

The in-office or power bleaching can give dramatic results almost immediately, and it can lighten up to 4 shades. Home care bleaching takes about 10 days or more before desired result is achieved, and can lighten the teeth for up to 2-3 shades.
