Between the ages of 11 and 15 is the most common time for orthodontic treatment, and for good reasons. By age 12 most, if not all, of the permanent teeth have erupted and are in place, and crooked teeth, gaps, and bad bites can easily be detected. These problems will hardly ever correct themselves, so this is when most parents decide to seek orthodontic treatment.
This is also a good time for orthodontic treatment because many negative associations of braces are not present. Many children in this age range undergo orthodontic treatment and are easily convinced to wear braces because they see their friends also wearing them.
Besides the benefits of fitting in with their friends, children at this age are growing rapidly, and orthodontists can usually take advantage of these growth spurts to help shape the bite and teeth correctly. Children at this age have also high a metabolism, which can help shorten overall treatment time and reduce the discomfort of orthodontic treatment.
