Orthodontics or Dentofacial orthopedics is the formal name of the dental specialty concerned with the diagnosis, prevention, interception, guidance and correction of bad bites.

If teeth are crowded, protrusive (sticking out), spaced too far apart, meet in an abnormal way, or do not meet at all, correction may be recommended. Braces and aligners are the “appliances” dentists and orthodontists most commonly use to guide teeth into proper positions. Once teeth are moved into proper alignment, retainers are used to preserve and stabilize the results of the orthodontic treatment.
