Orthodontics is a specialty of dentistry that is officially known as Orthodontics and Dentofacial Orthopedics. The purpose of orthodontics is to treat any type of malocclusion, or "bad bite". A malocclusion is any irregularity in the correct positioning of teeth that affects the proper way that teeth of the two jaws should fit together when we close our mouth. Some examples of malocclusion are crowded teeth, overbites, underbites or jaws that are out of alignment.
