If you want to improve the look and function of your smile, any age is a great age to see the orthodontist. The American Association of Orthodontists recommends that children first visit an orthodontist around the age of 7. This allows the orthodontist to monitor each individual's development and time treatment accordingly. There is no cost or obligation for this service. Orthodontic treatment is not exclusive to children and teens. In fact, about one in every five orthodontic patients are over the age of 21. Whether you're considering treatment for yourself, or for a child, any time is a good time to visit the orthodontist.
