Most oral surgeons are not MDs. They hold a dental degree (DDS or DMD) and complete a hospital-based surgical residency, but they do not attend medical school. Some oral surgeons choose to earn a medical degree in addition to their dental degree, but this is optional and not required to practice oral and maxillofacial surgery.
What Degree Oral Surgeons Actually Hold
Every oral surgeon starts with a dental degree, either a Doctor of Dental Surgery (DDS) or a Doctor of Dental Medicine (DMD). These two degrees are clinically identical and cover the same curriculum. The difference in name simply depends on which dental school the surgeon attended.
After dental school, oral surgeons complete a minimum of four years in a hospital-based surgical residency. This is where the training diverges sharply from general dentistry. During residency, oral surgery residents rotate through hospital services alongside medical residents. They spend at least 20 weeks on anesthesia rotations (including pediatric anesthesia), at least 8 weeks on medicine or medical subspecialty services, and complete training in trauma, general surgery, and intensive care. This hospital-based experience is what qualifies them to perform surgery, administer deep sedation, and manage complex medical situations, not a medical degree.
The Dual-Degree Path
Some oral surgery residency programs integrate medical school into the training, producing surgeons who hold both a dental degree and an MD. These programs run about six years instead of four. At Mayo Clinic, for example, residents spend their first year primarily on oral surgery with some medical school coursework, then complete two full years of medical school (including licensing exams), followed by rotations in general surgery, plastic surgery, trauma, and anesthesia before finishing with advanced oral surgery training in years five and six.
Dual-degree surgeons pass the same U.S. Medical Licensing Examination (USMLE) steps that all physicians complete. They earn a legitimate MD alongside their dental degree. However, the American Board of Oral and Maxillofacial Surgery does not require a medical degree for board certification. The board certification process is the same regardless of whether the surgeon holds one degree or two: a 300-question written exam covering 11 subject areas, followed by an oral exam with 12 case-based scenarios totaling 144 minutes.
Does the MD Make a Difference in Patient Care?
For most procedures you’d see an oral surgeon for, the presence or absence of an MD does not change your experience or outcomes. Wisdom tooth removal, dental implants, bone grafts, and jaw realignment surgery all fall within the standard training that every oral surgery resident receives during their four-year minimum residency. All oral surgeons, regardless of degree, train in the same hospital environments, manage the same types of anesthesia, and handle the same surgical complications.
Where the dual degree becomes more relevant is at the far end of the specialty’s scope. Oral and maxillofacial surgeons who focus on reconstructive facial surgery, cleft lip and palate repair, or complex craniofacial trauma may find the additional medical training useful. These procedures overlap significantly with plastic surgery and require deep familiarity with systemic medical management. Cleveland Clinic draws a distinction between the simpler end of the specialty (extractions, implants, bone grafts) and the more complex end (reconstructive facial surgery, jaw implants, sleep apnea surgery, cancer treatment), though surgeons at both ends can hold either credential.
How Oral Surgeons Compare to Other Specialists
The confusion around oral surgeons and the MD title comes partly from how they practice. Unlike most dentists, oral surgeons work in hospital operating rooms, administer general anesthesia, manage trauma patients, and treat conditions that span the boundary between medicine and dentistry. Their residency training mirrors surgical residency in many ways. But their licensing and legal authority to practice comes through dental boards, not medical boards. An oral surgeon without an MD holds a dental license. An oral surgeon with an MD may hold both a dental and medical license, though practice patterns vary by state.
Your general dentist refers you to an oral surgeon for problems that go beyond routine dental care: impacted wisdom teeth growing at odd angles or trapped beneath bone, dental implants requiring precise placement into the jawbone, misaligned jaws affecting chewing or facial structure, infections that have spread into bone, facial injuries from accidents, or suspicious oral lesions that need biopsy. None of these referral decisions hinge on whether the oral surgeon also holds an MD.
Total Training Timeline
To put the training in perspective, here’s what the path looks like from start to finish:
- Single-degree track: 4 years of college, 4 years of dental school, 4 years of surgical residency. That’s 12 years minimum after high school.
- Dual-degree track: 4 years of college, 4 years of dental school, 6 years of combined medical school and surgical residency. That’s 14 years minimum.
Both tracks produce board-eligible oral and maxillofacial surgeons. Both require passing the same board certification exams through the American Board of Oral and Maxillofacial Surgery. The dual-degree surgeon simply has additional medical training and credentials layered on top of an already extensive surgical education. If your oral surgeon does not have an MD, that is the norm, not the exception.
