The length of treatment varies depending on the complexity of the orthodontic problem that requires correction, growth and tissue response to treatment as well as the level of patient cooperation during their treatment. Orthodontic care requires a team approach in which the family dentist, the orthodontist and the patient play key roles that can impact the length of treatment and the quality of the end result. Generally, the length of comprehensive orthodontic treatment can range from approximately 18 months to 30 months, depending on treatment options and individual characteristics.
