Because monitoring growth and development is crucial to managing some orthodontic problems well, the American Association of Orthodontists recommends that all children have an orthodontic screening no later than age 7.
By the age of 7, the first adult molars erupt, establishing the back bite. During this time, an orthodontist can evaluate front-to-back and side-to-side tooth relationships. Some orthodontic problems may be easier to correct if treated early. Waiting until all the permanent teeth have come in, or until facial growth is nearly complete, may make correction of some problems more difficult.
Early evaluation provides both timely detection of problems and greater opportunity for more effective treatment. Prudent intervention guides growth and development, preventing serious problems later. When orthodontic intervention is not necessary, an orthodontist can carefully monitor growth and development and begin treatment when it is ideal.
