Stained teeth are usually caused by coffee, tea, tobacco, increased age, too much fluoride, or exposure to certain antibiotics during tooth development. Tooth whitening is a good option for reducing certain types of staining, but not all. We will be happy to discuss tooth-whitening options with you. There are three basic approaches for whitening teeth: using over-the-counter products; following a doctor-recommended in-home system; or following an in-office procedure. In our experience, the most predictable option is the doctor-recommended in-home system, in which a whitening solution (carbamide peroxide) is placed in a plastic tray that has been custom-fit to your mouth.
