Teeth whitening is a common cosmetic dental procedure that uses oxidizing agents like hydrogen peroxide to lighten tooth color. There are two main whitening methods - an in-office treatment that uses a high concentration of peroxide for a short time, or a take-home treatment involving wearing a low concentration of peroxide for several hours a day over 5 to 14 days. Both work by the peroxide entering the tooth structure and oxidizing internal stains. While whitening can significantly lighten many stains, some like tetracycline staining may be resistant and require prolonged treatment. Side effects can include temporary tooth sensitivity. Faded results may fade over time as well.
