The teenage years are the most common time for comprehensive orthodontic treatment before most or all of the permanent teeth are present in the mouth. Braces straighten the teeth and help to correctly align the bite. By age 12, most, if not all, permanent teeth have erupted and this is when crooked teeth, spaces or "bad bites" can easily be noticed. These problems rarely ever correct themselves, so this is when most parents decide to seek orthodontic treatment.

If a Phase 1 treatment was completed, typically, Phase II treatment is completed once most of the permanent teeth have erupted.

For many teenagers, wearing braces is a part of life - and an important part because a beautiful and healthy smile can boost one's self-confidence.
