Oral and maxillofacial surgery is a surgical specialty focused on treating diseases, injuries, and defects of the mouth, jaws, face, and skull. It sits at the intersection of medicine and dentistry, covering everything from routine wisdom tooth removal to complex facial reconstruction after trauma or cancer. These surgeons operate on both hard tissue (bone) and soft tissue (skin, muscle, nerves) across the entire face and jaw region.
What the Specialty Covers
The scope of oral and maxillofacial surgery is broader than most people expect. While the most common procedures involve tooth extractions and dental implants, the specialty extends to treating facial fractures, jaw deformities, tumors and cysts of the mouth and face, temporomandibular joint (TMJ) disorders, and even obstructive sleep apnea. Cosmetic procedures like reshaping the chin or correcting age-related changes to the face also fall within this field.
The anatomical territory these surgeons work in includes the jawbones, cheekbones, eye sockets, forehead, nose, salivary glands, and the soft tissues surrounding all of them. When a tumor needs to be removed from the jaw or a car accident shatters the bones of the mid-face, an oral and maxillofacial surgeon is typically the one performing the operation and rebuilding what was lost.
Tooth Extractions and Dental Implants
The bread and butter of most oral and maxillofacial surgery practices is dentoalveolar surgery, which means operations on the teeth and the bone that holds them. This includes removing impacted wisdom teeth, extracting severely decayed or broken teeth, draining dental abscesses, and biopsying suspicious lesions inside the mouth. A single tooth extraction typically takes about 30 minutes, though more involved procedures can run one to two hours.
Dental implants are another major part of the workload. These surgeons plan and place the titanium posts that serve as artificial tooth roots, and they handle the bone grafting or tissue preparation that’s often needed before an implant can go in. For patients who have lost significant jawbone over time, advanced techniques exist to anchor implants into denser bone higher in the skull, like the cheekbone area. This kind of complex planning requires detailed imaging and careful coordination between the surgeon and the dentist who will build the final replacement teeth.
Corrective Jaw Surgery
Orthognathic surgery, the technical term for corrective jaw surgery, repositions the upper jaw, lower jaw, or both to fix problems with how they line up. This is used to treat significant overbites, underbites, jaws that are too small or too large, and jaws that have grown unevenly. It also plays a role in treating obstructive sleep apnea, cleft lip and palate, and TMJ disorders.
During the procedure, the surgeon makes incisions inside the mouth to access the jawbone, creates precise cuts in the bone, moves the jaw into its new position, and secures it with surgical screws, plates, or wires. In some cases, bone is removed, reshaped, or added. Because the incisions are usually made inside the mouth, visible scarring is minimal. This surgery is almost always planned in partnership with an orthodontist, who aligns the teeth before and after the operation so that the bite functions properly once healing is complete.
Facial Trauma and Fractures
Facial fractures from car accidents, falls, sports injuries, or assaults are a core part of what oral and maxillofacial surgeons treat. The most common fractures they manage include broken noses, fractured eye sockets, cheekbone fractures, broken jaws (both upper and lower), and complex mid-face fractures that involve multiple bones at once.
Treatment follows two basic steps: reduction, which means moving the broken bones back into their correct positions, and fixation, which means holding them still long enough to heal. Simple fractures can sometimes be reset without surgery. Complex fractures with multiple broken bones require reconstructive surgery, where the surgeon uses titanium plates, screws, and wires to stabilize everything. The two primary goals of facial reconstructive surgery after trauma are restoring function (chewing, swallowing, breathing, vision) and optimizing appearance.
Oral Cancer and Tumor Removal
Oral and maxillofacial surgeons diagnose and treat cysts, benign tumors, and malignant cancers of the mouth, jaws, and salivary glands. Their role in cancer care goes well beyond just removing the tumor. At major medical centers like Mayo Clinic, these surgeons coordinate multidisciplinary teams that guide patients through diagnosis, staging, tumor removal, reconstructive surgery, dental rehabilitation, speech therapy, and long-term survivorship care.
Reconstruction after tumor removal is one of the most technically demanding parts of the specialty. It can involve transferring skin, bone, and nerves from other parts of the body to rebuild sections of the jaw or face. The goal is to return patients to the best possible level of appearance and function, which in practical terms means being able to eat, speak, and breathe normally while looking as close to their pre-surgery appearance as possible.
TMJ Disorders and Facial Pain
The temporomandibular joint connects your lower jaw to your skull, and problems with it can cause clicking, locking, pain while chewing, and chronic headaches. Oral and maxillofacial surgeons are trained to diagnose and manage these disorders using both surgical and nonsurgical approaches. Their training also includes sorting out the broader picture of head, neck, and facial pain, since TMJ symptoms can overlap with other conditions like nerve disorders or referred pain from the neck.
Anesthesia in the Office Setting
One thing that sets oral and maxillofacial surgeons apart from most other dental specialists is their extensive training in anesthesia. They are qualified to administer everything from mild sedation to full general anesthesia right in their office, which is why wisdom tooth removal and implant surgery can happen outside a hospital.
Safety standards for office-based anesthesia are rigorous. A dedicated team member, separate from the surgeon, must continuously monitor you throughout the procedure. During deep sedation or general anesthesia, that person has no other responsibilities. The office must have monitoring equipment in both the procedure room and the recovery area, along with resuscitation equipment and emergency medications immediately on hand. Staff must maintain current certifications in advanced cardiac and basic life support.
Training and Qualifications
Becoming an oral and maxillofacial surgeon requires completing dental school followed by a minimum of four years in a hospital-based surgical residency. That residency includes rotations alongside medical residents in areas like general surgery, anesthesiology, internal medicine, and emergency medicine. Some surgeons choose to also complete medical school, earning both a dental degree and a medical degree, though a medical degree is not required to practice the specialty. All told, the training path takes between 10 and 14 years after college, depending on whether the surgeon pursues a dual degree.
This combination of dental and surgical hospital training is what allows these surgeons to work across such a wide range of procedures, from a 30-minute tooth extraction under local anesthesia to a multi-hour facial reconstruction under general anesthesia in a hospital operating room.
