This is the process of chemically bleaching your teeth in order to attain brighter smile. This procedure can either be done in office in about two hours, or through take home trays in about two weeks. A carbamide or hydrogen peroxide solution is used to gently lighten the shade of your teeth. The chemical bleach removes the stains your teeth pick up over time from coffee, soda, red wine, and other colored foods. It is important to maintain a white diet through the process of bleaching so as not to stain your teeth while bleaching them. A list of proper foods will be given to you. Whitening has no known long term negative effects, but can result in some short term sensitivity during treatment. This sensitivity will go away once your treatment is completed.
