In teens, Orthodontic treatment usually starts between the ages of 12 and 16 because most permanent teeth have erupted by this time. Orthodontic problems like gaps, crowding, malocclusions and alignment are easily detected in teenagers. Bone and jaw structures have sufficiently formed to allow orthodontic treatment to begin but are still soft enough to move teeth easily. Most importantly, if your teenager has gaps, crooked, or protruding teeth, they may feel self-conscious and hide their smile. Many teenagers become very concerned with how they may be perceived and treated by their peers. Confidence and positive self-esteem can help your teen be successful through their education, social and future career goals. Often a straight smile helps their confidence.
