Teeth can be moved at any age. During the teenage years, treatment may take advantage of remaining jaw growth to correct the bite problem, especially around the growth spurt stage (at 12 years in girls and 15 years in boys). Orthodontic treatment is no longer just for children and teens. Many adults choose to receive orthodontic treatment because they understand the importance of maintaining their health, and they want to feel better about their appearance. Orthodontic treatment at this stage requires the use of fixed appliances (braces) in combination with removable appliances. Adults are not growing and sometimes experience worn, damaged, missing teeth and/or loss of the bone that supports the teeth. For these reasons, adult treatments normally require coordination between the orthodontist, oral surgeon, periodontist, endodontist and family dentist to assure the complete rehabilitation of the bite. In addition, treatment may take longer due to these complicating factors and the full maturity of the bone.
