Corrective jaw surgery – called orthognathic surgery – is performed by oral and maxillofacial surgeons to realign jaws and teeth. Orthodontists correct a person’s bite if only the teeth are misaligned. Corrective jaw surgery may be necessary if the jaw is misaligned. Jaw misalignment can be caused by injuries, birth defects or different growth rates of the jaws. Surgery can improve basic functions, such as breathing, chewing and speaking. Your dentist, orthodontist and OMS will work together to determine whether you are a candidate for corrective jaw surgery.
