Cosmetic dentistry, an oral health care specialty, improves the smile of patients using several techniques. The most common cosmetic dentistry treatment is teeth whitening. Professional teeth whitening provides the patient with dramatic results in less time than at-home treatments. A person’s smile may also be improved with dental bonding. For bonding procedures, the dentist applies a permanent material to the surface of the teeth. Bonding is an effective treatment for chipped teeth. If bonding is used to whiten teeth, the paste may be a few shades lighter than the patient’s natural teeth. Veneers and cosmetic contouring are techniques used by the dentist to improve the shape and color of the patient’s teeth.
