Yes they do. As of 2016, there were 1,690,000 adults being treated by U.S. and Canadian members of the American Association of Orthodontists.
Am I too old for orthodontic treatment?
You are never too old for orthodontic treatment. Your orthodontist considers many variables when developing your customized treatment plan, but age is rarely a deciding factor.
Can your teeth shift as an adult?
Yes. Adult teeth do and can shift over time, whether or not you had braces when you were a teenager.
