Most children with invisible (lingual) or other dental braces begin active orthodontic treatment between ages 8 and 14. However, the American Association of Orthodontists recommends an orthodontic check-up no later than age 7.

Eligibility for lingual braces is not a question of age as much as it is a question of tooth length. There is a minimum crown length that must exist in order for there to be enough room for the braces to be glued on the insides of the teeth. The length is not usually present in children, sometimes available in teenagers, and usually not a problem in adults.
