Oral and maxillofacial surgeons require 4 to 6 years of additional formal university training after dental school. Oral surgery is an internationally-recognized surgical specialty. In some countries, including the United States, it is a recognized specialty of dentistry by the American Dental Associations.
Oral and maxillofacial surgery procedures include wisdom teeth removal, simple tooth extractions, reconstructive oral surgery, dental implants, treatment of oral infections, and the repair of facial, mouth, jaw and tooth injuries.
