Between the ages of 11 and 15 is the most common time for orthodontic treatment. By 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 children are very often able to be convinced to wear braces because they see their friends wearing them, too, and want to fit in.
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. And children at this age have high metabolisms, which can help shorten overall treatment time and reduce the discomfort of orthodontic treatment.
