Your dentist can whiten teeth dramatically using various forms of hydrogen peroxide. One form,
carbamide peroxide, is most often used in the form of a gel, and placed into a special tray that is custom-fitted to your
teeth. The tray is worn in the mouth for about an hour a day for two to four weeks. When in
contact with the teeth, the carbamide peroxide releases oxygen that releases the stain on your teeth. This process is
safe and effective with only a few temporary side effects. This treatment can be applied at home under periodic supervision
by your dentist.
