About Teeth Whitening
What causes tooth discoloration?
Many factors affect tooth color. Genetics is one factor; some people just have whiter teeth than others. Other factors include dark foods and beverages (including coffee, soda, and tea), age, medications (such as tetracycline), and tooth trauma.
How does teeth whitening work?
Opalescence whitening gels contain an active whitening ingredient – either carbamide peroxide or hydrogen peroxide. Active oxygen molecules from the whitening agent are able to pass though the enamel of the teeth, where they react with and neutralize the discolored molecules that cause discoloration. The active oxygen molecules spread, whitening the entire tooth. As a result, you have a brighter, whiter smile.
Will whitening cause tooth sensitivity?
Tooth sensitivity can occur as a result of whitening. If sensitivity occurs, it is temporary and typically disappears within a few days after the completion of whitening treatments. Desensitizing treatments can be used to help treat or prevent sensitivity if it occurs. Contact your dentist to learn more about these treatment options. If sensitivity persists, contact your dentist.
Will whitening weaken my teeth?
No. Whitening has not been shown to weaken teeth.
How long do whitening results last?
Teeth whitening results are very stable, leaving you with a stunning smile long after treatment is over. However, there are a few factors that can make teeth lose their brightness. Things like diet and certain habits may affect the length of your whitening results.
