Orthodontics is the branch of dentistry which deals with the causes, prevention and treatment of irregularities in the position of the teeth. In the past, whenever anyone suffered problems with teeth, their only option was to keep the teeth as long as they could until they lost them through decay, gum disease or accident. Fortunately today, through proper care at home and with professional treatment, most people are able to keep a healthy and sound set of teeth throughout their lifetime. Orthodontic treatment plays an important role in healthy teeth. Not only does it deal with the health of our teeth and gums (since crooked teeth and poor jaw alignment are prime causes of decay and gum disease), it also deals with the esthetics of the mouth, for orthodontic treatment can transform severe problems into beautiful, shining smiles. The benefits naturally follow. Following are some commonly asked questions surrounding orthodontics.
