The American Board of Orthodontics was established in 1929 and was the third certifying board in the health professions and the first in dentistry.

Board certification is an elective process and not every orthodontist undertakes this rigorous, lengthy and ongoing examination process. It is intended to provide assurance to the public that an orthodontic specialist has successfully completed an approved educational program and an evaluation process which includes an examination designed to assess the knowledge, skills and clinical expertise required to provide quality patient care. Completion of this process is an indication of an orthodontist’s commitment to establish and maintain the highest standards of clinical excellence in orthodontics.
