Cosmetic dentistry is generally used to refer to any dental work that improves the appearance(though not necessarily the functionality) of teeth, gums and/or the bite.  Many dentists refer to themselves as “cosmetic dentist” regardless of their specific education, specialty, training, and experience in this field. The only dental specialty recognized by the American Dental Association (ADA) that provides advanced postgraduate training in cosmetic dentistry is PROSTHODONTICS.
