An orthodontist is a dentist specialized in diagnosis and treatment of teeth and facial irregularities. Orthodontists must first attend college, and then complete a four-year dental graduate program at a university dental school or other institution accredited by the Commission on Dental Accreditation of the American Dental Association (ADA). They must then successfully complete an additional three-year residency program of advanced education in orthodontics.
 

Even that some general dentist can treat cases of malocclusion with dental braces, only dentists who have successfully completed this advanced specialty education may call themselves orthodontists.
