Typically, Phase II treatment is orthodontic treatment that involves placing braces on the patient once his or her permanent teeth have erupted. The braces straighten the teeth and help to correctly align the patient’s 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 by the patient or parent. These problems rarely ever correct themselves, so this is when most parents decide to seek orthodontic treatment for their children.

Children at this age are growing rapidly, and orthodontists can usually take advantage of these growth spurts to help align the bite and place the teeth in the proper position.

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.
