Orthodontia, also known as orthodontics and dentofacial orthopedics, was the first specialty created in the field of dentistry. An orthodontist, specialist in orthodontia, is limited to practice orthodontia only.
Whereas general dentists can provide orthodontic treatment along with other treatments for teeth like fillings, cleanings, and crowns. Orthodontists are concerned with the study and treatment of malocclusions (improper bites), which may be a result of tooth irregularity and/or disproportionate jaw relationships. Orthodontic treatment can focus on dental displacement only, or can deal with the control and modification of facial growth. In the latter case it is better defined as “dentofacial orthopedics”.
