In dentistry, oral surgery is a recognized specialty. It includes diagnosis, surgery and treatment of diseases and correction of defects for both health and aesthetic purposes of the tissues in the mouth, teeth, head, jaws, gums and neck.
Other things involved in oral surgery include wisdom teeth removal, dental implants, TMJ disorder, apicoectomy, corrective jaw surgery, facial trauma, osseous tissue surgery, oral pathology, bone grafts and anesthesia.
In other areas of the world (apart from the U.S.A), oral surgery is different from oral and maxillofacial surgery (OMS, OMFS or Maxfacs). The latter is a different branch of surgery which requires one to have practiced medicine and dentistry for no less than 8 years after graduating from college.
In Europe, oral surgery is defined as a dental specialty. To qualify for it, you need to have 3 years of post-university training.
Directive 2001/19/EC separates oral surgery from other medical or dental qualifications, like oral and maxillofacial surgery, which require both dental as well as medical training within the E.U.
It should be stated that in the U.S, there is no such equivalent to dental specialists to the European ‘oral surgeon’. In the United States, oral surgeons are those people who can be more appropriately describe as maxillofacial surgeons.
