Can braces change the shape of your face/jaw?

Possibly: Orthodontics may well be able to change the shape of your face and projection of your jaws and facial profile: it depends upon the severity of the problem, the age of the patient and whether or not orthognathic surgery is part of the treatment plan. If you have a severe overbite (overjet), braces can significantly reduce the projection of upper lips teeth and jaw. Genetics may make surgery needed.

It depends...: In an adult, braces alone don't change the shape of your jaw. They can change the way your lips drape for example if you had protruding teeth "overbite". Orthodontics combined with jaw surgery can change the shape of your jaw. Orthodontics combined with orthopedic appliances in a child may also change the shape of their jaw.

Yes: It can make it better.

Depends on treatment: Orthodontic treatment may or may not have an effect on facial profile or lip posture depending upon the nature of the treatment provided. There are instances where specific changes in soft tissue are part of the treatment plan. Your orthodontist can describe what effects should be expected in your particular case.

Braces and faces: It depends on how severe your teeth deviate from "normal" prior to treatment.

Yes: It's not the braces that change your face, it's the orthodontic treatment. Any dentist can put on braces and move teeth. An orthodontic specialist is trained in creating the best possible cranio-facial balance as well as the most stable, function, and attractive occlusion. Ask an orthodontist what can be done for you.
