Oral and Maxillofacial Surgery is the branch of dentistry that is concerned primarily with surgery on the teeth, jaws, and surrounding soft tissues.

Oral and maxillofacial surgery is used to treat many diseases, injuries and defects in the head, neck, face, jaws and the hard and soft tissues of the oral (mouth) and maxillofacial (jaws and face) region. Depending upon the jurisdiction, maxillofacial surgeons may require training in dentistry, surgery, and general medicine; training and qualification in medicine may be undertaken optionally even if not required.
