When Do You Need to See the Orthodontist?
The American Association of Orthodontists (AAO) recommends that all children have a check-up with an orthodontist specialist no later than age 7. At this time, the bite begins to be established when the first molars erupt (approximately age 6).
The incisors or the front teeth have also begun to erupt at this time, and problems can be detected, such as crowding, habits, deep bites, and some jaw discrepancies. Although most kids do not need treatment at this time, a timely evaluation will lead to significant treatment benefits moving forward and the immediate benefit of a parent's peace of mind. Adolescents and adults with fully developed dentition can seek a consultation from an orthodontist at any time
