Ideally, children should be evaluated orthodontically between 7-8 years of age by an orthodontist to make sure there are no issues that might need early intervention. Adolescents typically begin orthodontic treatment between 12-14 years of age, following the loss of the last primary (baby) tooth. For adults, orthodontic treatment can still occur at later stages in life. Dr. Y carefully analyzes the nature of each orthodontic issue and will discuss if it may benefit your health and smile.
