This branch of dentistry involves realigning teeth so they can fully perform their functional activity. In addition, it offers patients the opportunity to have a more harmonious and aesthetic smile. It may require prior devices such as widening the dental arches.

It is most commonly performed on children and adolescents because during this growth period, realigning teeth is easier and provides ample room for the orthodontist to maneuver. However, it can also be used by adults.
Specific procedures are used, such as the use of transparent aligners, to minimize discomfort for patients in their daily lives.
