Whereas conventional orthodontic treatment typically begins during the early teen years (age 11-13), early treatment, if your child would benefit from it, typically begins around age eight or nine. The goal of early treatment is to correct the growth of the jaw and certain bite problems such as an underbite. Early treatment also helps to make room for permanent teeth to come in properly, lessening the chance for extractions in the future.
Simply put, Phase One is early orthodontic treatment that is sometimes recommended to help or prevent bigger dental/orthodontic problems from occurring. Orthodontic appliances, retainer-like devices, or partial braces may be placed to prevent a problem from occurring, correct a current problem, or help to modify your child’s growth and dental development. It isn’t uncommon for a second phase of treatment to be needed after this first phase.
In simple terms, Phase Two orthodontic treatment usually involves full upper and lower braces, once all of the permanent teeth are in. When Phase One treatment has been successfully completed, the duration of the second orthodontic treatment phase may be reduced significantly and will require less complex treatment, reflecting the benefit of the earlier intervention.
