An orthodontist is a specialist in the diagnosis, prevention and treatment of dental and facial irregularities. All orthodontists are dentists, but only about 6% of dentists take the extra education to become an orthodontist. Admission to an orthodontic postgraduate program is extremely competitive and selective.
It takes many years to become an orthodontist and the educational requirements are demanding. An orthodontist must complete college requirements before starting a four-year graduate program at a dental school accredited by the American Dental Association (ADA). After dental school, at least two or three academic years of advanced specialty education in an ADA-accredited orthodontic program are required to be an orthodontist. The program includes advanced education in biomedical, behavioral and basic sciences. The orthodontic student learns the complex skills required to manage tooth movement (orthodontics) and guide facial development (dentofacial orthopedics). Only dentists who have successfully completed these advanced specialty education programs may call themselves orthodontists, such as Dr. Harmon.
