The American Association of Orthodontists recommends that children see an orthodontist as early as age seven. At this point the orthodontist will evaluate whether your child will need orthodontic treatment. Early treatment (also known as Phase One) typically begins around age eight or nine (Phase Two will begin around age 11 or older). The goal of early treatment is to correct the growth of the jaw and certain bite problems, such as underbite. Early treatment also helps to make room for permanent teeth to come in properly, lessening the chance of extractions in the future.
