How does tooth whitening work?

It’s a bleaching process that lightens discolorations of enamel and dentin using a mild solution of Carbamide Peroxide or Hydrogen Peroxide. Discoloration can be caused by many factors, including consumption of staining substances (coffee, tea, colas, tobacco), trauma, nerve degeneration, and old restorations. Research and clinical studies indicate that whitening teeth with Carbamide Peroxide or Hydrogen Peroxide under the supervision of a dentist is safe for teeth and gums.

How long will the results last?

The teeth will always be lighter than they once were. However, some patients may need a tooth whitening “touch-up” for a few days, once or twice a year. In order to maintain the whitest tooth shade possible, it is best to avoid substances like coffee, tea, red wine and tobacco. Find out more about tooth whitening from the American Dental Association.
