Orthodontics is a specialty of dentistry that is concerned with the study and treatment of malocclusions, which may be a result of tooth irregularity, disproportionate jaw relationships, or both. The word comes from the Greek words ortho meaning straight and odons meaning tooth. There are many reasons why orthodontic therapy may be desired, including to allow proper eruption of teeth.
