An oral surgeon is a dental specialist trained to perform surgery on the mouth, jaw, and face. Formally called an oral and maxillofacial surgeon, this is the most surgically intensive specialty in dentistry. While a general dentist handles cleanings, fillings, and routine extractions, an oral surgeon steps in when a case requires cutting into bone, administering general anesthesia, or reconstructing facial structures after trauma or disease.
What Oral Surgeons Actually Do
The day-to-day work of most oral surgeons centers on extracting teeth, particularly impacted wisdom teeth that are trapped beneath the gumline or growing at odd angles. But the specialty extends well beyond extractions. Oral surgeons place dental implants (titanium posts screwed into the jawbone to replace missing teeth), perform biopsies on suspicious growths inside the mouth, treat infections that have spread into deeper tissue, and surgically expose teeth that haven’t come in properly so orthodontists can guide them into place.
They also handle more complex procedures that overlap with medical surgery. These include repairing broken facial bones, reconstructing jaws after tumor removal, correcting birth defects like cleft lip and palate, and performing corrective jaw surgery for people whose upper and lower jaws don’t align properly. That jaw misalignment can cause chronic pain, difficulty chewing, and even obstructive sleep apnea, where the airway collapses during sleep.
Facial Trauma and Reconstruction
Oral surgeons are often the specialists called in for facial injuries. Fractures can involve the lower jaw, upper jaw, cheekbones, eye sockets, or the roof of the mouth, and injuries frequently combine bone breaks with soft tissue damage like deep cuts. Car accidents, falls, sports injuries, and assaults are common causes. The surgeon’s job is to realign broken bones, repair damaged soft tissue, and restore the way the teeth fit together. Because the face is both structurally complex and cosmetically important, these repairs require precision that general surgeons typically don’t train for.
Jaw Surgery for Structural Problems
Corrective jaw surgery, called orthognathic surgery, repositions the upper jaw, lower jaw, or both to fix skeletal problems that braces alone can’t correct. People with severely receding chins, protruding jaws, or jaws that have grown unevenly may need this procedure. It treats functional problems like difficulty biting and chewing, TMJ disorders that cause chronic jaw pain, and obstructive sleep apnea caused by a narrow airway. Recovery typically involves weeks of a modified diet and gradual return to normal jaw function, and the surgery is usually coordinated with an orthodontist who handles braces before and after the procedure.
Bone Grafting and Implant Placement
When someone has been missing teeth for a while, the jawbone in that area gradually shrinks. If there isn’t enough bone left to anchor a dental implant, an oral surgeon performs a bone graft to rebuild the area. This can mean adding bone material to widen a thin jaw ridge or lifting the floor of the sinus cavity to make room for an implant in the upper jaw. The grafted bone needs several months to integrate before the implant itself is placed. Oral surgeons handle the full process: evaluating whether you’re a candidate, preparing the bone, placing the implant, and managing any complications.
Anesthesia Training Sets Them Apart
One of the biggest differences between oral surgeons and other dental specialists is their ability to put patients fully under. Oral surgeons train extensively in administering three levels of sedation: moderate sedation (where you’re drowsy but can respond to voice commands), deep sedation (where you’re nearly unconscious and may need help breathing), and general anesthesia (where you’re completely unconscious). This training happens in hospital settings during residency, and it allows oral surgeons to safely perform these sedation levels right in their office rather than requiring a hospital operating room. For patients, this means procedures like wisdom tooth removal or implant placement can happen under full sedation in a single office visit.
Biopsies and Oral Pathology
Oral surgeons play a key role in catching oral cancer and other diseases early. When a dentist spots an unusual lump, sore, or discolored patch inside your mouth, they often refer you to an oral surgeon for a biopsy. The surgeon removes a small sample of tissue (or the entire growth, depending on its size and location) and sends it to a lab for analysis. Growths that interfere with chewing or speaking, or that are suspected to be cancerous, are typically excised completely. If a biopsy comes back showing cancer, the oral surgeon may also perform the surgery to remove the tumor and reconstruct the surrounding tissue.
How Long Training Takes
Becoming an oral surgeon requires more training than almost any other dental specialty. The path starts with four years of dental school to earn a DDS or DMD degree. After that comes a minimum of four years in a hospital-based surgical residency, where trainees rotate through anesthesia, general surgery, internal medicine, and other medical services alongside their oral surgery training. Some oral surgeons also complete medical school on top of dental school, earning a dual MD degree, though this isn’t required to practice. In total, the training takes a minimum of 12 years after high school.
After residency, oral surgeons can pursue board certification through the American Board of Oral and Maxillofacial Surgery. The process involves a 300-question written exam covering 11 subject areas, followed by an oral exam where candidates walk through clinical cases for nearly two and a half hours. Passing both earns the title of Diplomate, which signals that the surgeon has met the highest standard of competency in the field.
Oral Surgeon vs. General Dentist
Your general dentist can pull a tooth that’s fully erupted and straightforward to remove. They can also perform minor soft tissue procedures and administer local anesthesia (the numbing shot). But when a tooth is buried in bone, when the jaw itself needs to be cut and repositioned, or when you need to be put under general anesthesia, you’ll be referred to an oral surgeon. Think of the relationship like a family doctor referring you to a specialist: the general dentist manages your routine care and calls in the oral surgeon when the case demands surgical expertise, hospital-level anesthesia training, or both.
Oral surgeons also differ from other dental specialists like periodontists (who focus on gums) or endodontists (who do root canals). While there can be some overlap, particularly with dental implants, oral surgeons are the only dental specialists trained to manage the full range of surgical procedures across the entire face and jaw skeleton.
