Adolescent Treatment In most cases, the ideal age for braces, and other orthodontic treatments, is between 10 and 14 years of age. Adolescent orthodontics helps improve self-image by changing the appearance of teeth, and also improving the soft tissue features of the face.  Other than the cosmetic benefits of orthodontic treatment, adolescents also experience fewer cavities, less wear of the teeth and an improved environment for healthy gums.
