Age 4 or older are good for a first visit to a dentist as a preventive care. The American Association of Orthodontists recommends that the initial orthodontic evaluation should occur no later than age 7 or at the first sign of orthodontic problem. Permanent teeth have already erupted at this time so detecting problems at an earlier age makes easier to treat them and will benefit children in the long-run. Early prevention could help to avoid problems related to malocclusions, such as difficulty to proper brush and floss, accidental chipping, tongue-thrusting habits or speech impediments. Early treatment is also known as Phase-One, usually beginning around age 8-9 to correct growth of the jaw, certain bite problems and help to make room for permanent teeth. It performs all the treatments needed before the adult teeth develop. The goal is minimize skeletal discrepancy that might interfere with normal pattern of growth or the eruption of permanent teeth besides, prepare the oral environment.
