Oral and maxillofacial surgery is defined by the American Dental Association as the specialty of dentistry which includes the diagnosis, surgical and adjunctive treatment of diseases, injuries and defects involving both the functional and esthetic aspects of the bone and soft tissues of the oral and maxillofacial region.
In plain English, this means oral and maxillofacial surgeons do all kinds of surgery involving the mouth, teeth, jaws and face. Oral and maxillofacial surgeons reconstruct faces shattered by car accidents and gunshots, remove tumors and cancerous lesions, correct bites by surgically repositioning the jaws, place dental implants, repair cleft palates, perform all kinds of facial cosmetic surgery, and extract impacted wisdom teeth.
Even though oral and maxillofacial surgeons perform many of the same procedures as plastic surgeons and other medical specialists, oral and maxillofacial surgery is a specialty of dentistry. All OMSs are dentists, though some also hold medical degrees, and the practice of oral and maxillofacial surgery is regulated by state dental boards rather than medical boards.
