The American Association of Orthodontists recommends that the initial evaluation should occur at the first sign of orthodontic problems or no later than age 7. Starting a tretament early will produce optimal results and significantly reduce the amount of time and expense. Usually, at age 7, the first adult molars emerge, defining the back bite. This is when your orthodontic can examine and evaluate tooth alignment and diagnose possible problems. Remember, early detection and proper care prevents future serious problems. An adequate orthontic treatment can produce great results at any age, but it is important to get timely evaluation and if necessary, treatment.
