Should an orthodontist have a DMD or DDS?

DMD (Doctor of Dental Medicine) and DDS (Doctor of Dental Surgery) are two different degrees that are awarded to dentists. There is no significant difference between the two degrees in terms of the education required or the scope of practice. Both DMD and DDS holders must complete a four-year undergraduate degree, four years of dental school, and pass board exams to become licensed dentists.

Orthodontists are dentists who have specialized in orthodontics, which is the branch of dentistry that deals with the diagnosis, prevention, and treatment of dental and facial irregularities. To become an orthodontist, dentists must complete an additional two to three years of residency training in orthodontics after completing dental school.

So, to answer your question, an orthodontist can have either a DMD or DDS degree, as both degrees are recognized as equivalent qualifications for practicing dentistry.
