Orthodontics is a specialized field of dentistry that focuses on the diagnosis, prevention, and correction of malocclusions, or misalignments of the teeth and jaws. Orthodontists receive additional training beyond dental school to become specialists in orthodontics. While all orthodontists are dentists, not all dentists are orthodontists.
Orthodontic treatment can be used to improve the appearance of the smile, as well as to correct functional problems such as difficulty chewing or speaking. Orthodontists use a variety of appliances, such as braces and clear aligners, to move teeth into their proper positions.
