The biggest difference is that adults don’t have the benefit of a jaw that is still growing. While that doesn’t mean treatment can’t happen, it does mean it might be more involved. Some adults may require jaw surgery. But there are other things that can affect the outcome of adult treatment. Adults are more likely to suffer from gum disease or have previous dental work that will need to be taken into account. Some medications, as well as habits such as smoking or clenching or grinding the teeth can impact treatment, as well. No matter what issues you face, however, a trained orthodontist can work with you to help you achieve your smile goals.
