Orthodontics can boost a person's self-image as the teeth, jaws and lips become properly aligned, but an attractive smile is just one of the benefits. Alleviating or preventing physical health problems is just as important.

Without treatment, orthodontic problems may lead to tooth decay, gum disease, bone destruction and chewing and digestive difficulties. A "bad bite" can contribute to speech impairments, tooth loss, chipped teeth and other dental injuries.
