Orthodontics involves the diagnosis, prevention and treatment of structural problems involving the jaws and malocclusion commonly known as bad bites. Orthodontics in children are mostly used to straighten teeth after permanent teeth are erupted and adequate room has been created from orthopedic functional appliances. Orthodontics in adults can be used for the same condition as well as TMD, or more commonly known as TMJ pain. Orthodontic problems can affect your dental and general health as well as your personal appearance.
