Does my child need braces? Do I need braces? Sometimes it can be obvious if you or someone you know needs orthodontic treatments, other times it may be more difficult to tell. The best thing to do is have an initial evaluation by age 7 which will allow the orthodontist to take advantage of future growth potential and properly guide the eruption of the permanent teeth. However, even as an adult there are still orthodontic treatments that can correct your bite and align your teeth.
