TMJ surgery is primarily performed by oral and maxillofacial surgeons, a dental specialty focused on surgical treatment of the mouth, teeth, and jaws. These surgeons complete dental school followed by six years of hospital-based surgical and anesthesia training. In some cases, plastic surgeons or ear, nose, and throat (ENT) specialists also perform TMJ procedures, particularly total joint replacements.
Oral and Maxillofacial Surgeons
Oral and maxillofacial surgeons (often abbreviated OMS) are the specialists most commonly trained to operate on the temporomandibular joint. Their residency training covers the full range of jaw surgeries, from minimally invasive joint flushes to open joint reconstruction. To become board-certified, they must graduate from an accredited dental school, complete an accredited surgical residency, hold an independent practice license, and pass both a written qualifying exam and an oral certifying exam through the American Board of Oral and Maxillofacial Surgery.
TMJ arthroscopy, which involves inserting a tiny camera into the joint space, requires especially extensive experience and specialized training. Not every oral surgeon routinely performs TMJ procedures, so case volume matters. The American Board of Oral and Maxillofacial Surgery recommends asking your surgeon how often they perform the specific procedure in a given month or year.
Other Specialists Who Operate on the TMJ
For complex cases like total joint replacement, plastic and reconstructive surgeons and ENT surgeons may also be qualified. Clinical guidelines from the Japanese Society for Temporomandibular Joint list specialists certified by oral and maxillofacial surgery boards, plastic surgery boards, and otolaryngology boards as eligible to perform total TMJ replacement, provided they have sufficient experience in open TMJ surgery and have completed cadaver-based surgical training or a manufacturer-sponsored joint replacement course.
In practice, the surgeon who performs your procedure depends on the complexity of the case and who has the most relevant experience at your hospital or surgical center. A total joint replacement, for example, demands particularly difficult and high-risk techniques, making the individual surgeon’s track record more important than the letters after their name.
Types of TMJ Surgery
The procedure you need shapes which surgeon you see. TMJ surgeries range from office-based to major open operations.
Arthrocentesis is the simplest option. Two needles are placed into the upper joint space, and saline is flushed through to wash out inflammatory debris and break up adhesions. It can be done under local anesthesia and is preferred for its lower invasiveness and lower cost.
Arthroscopy uses a small camera (about 1.2 mm in diameter) inserted through a cannula into the joint. This gives the surgeon a direct view of the joint space, allowing them to cut adhesions, flush the joint, and inject anti-inflammatory medication into inflamed tissue when needed. Because it requires specialized equipment and skill, arthroscopy is less widely available than arthrocentesis.
Open joint surgery and total joint replacement are reserved for end-stage TMJ disease. These involve larger incisions, direct access to the joint structures, and in the case of total replacement, implanting a prosthetic joint. Recovery is longer and the risks are higher.
When Surgery Becomes an Option
Surgery is not a first-line treatment for TMJ disorders. Insurers typically require documentation of three to six months of nonsurgical management before approving a surgical procedure. That conservative phase usually includes some combination of physical therapy, medication, behavioral therapy (such as cognitive behavioral therapy or relaxation techniques), and a removable oral appliance like a splint, unless you can’t open your mouth wide enough to use one.
If those approaches fail, your dentist or physician can refer you to an oral and maxillofacial surgeon for a consultation. Some OMS offices require a referral; others accept self-referred patients. The American Association of Oral and Maxillofacial Surgeons notes that patients can now find surgeons directly online, though having a referral helps ensure continuity of care and may be required by your insurance plan.
What Insurance Typically Requires
TMJ surgery often falls under medical insurance rather than dental insurance, but coverage varies widely. One major insurer, Aetna, requires that all TMJ surgery requests go through a dedicated review unit. You’ll need to submit a detailed history, physical exam findings, imaging reports, and records showing three or more months of documented nonsurgical treatment along with the specific results of that treatment. Your proposed surgical plan must also be included. Checking with your insurance provider before scheduling a consultation can save significant time and frustration.
Success Rates and Recovery
Outcomes vary by procedure, but the numbers are generally encouraging. Arthroscopic surgery has been shown to reliably reduce pain and improve how far patients can open their mouths. In one study of patients whose TMJ pain hadn’t responded to conservative treatment, arthroscopy was successful in all cases for both pain reduction and improved jaw opening. Among patients with TMJ pain who underwent corrective jaw surgery, about 80% were pain-free one year later.
Recovery after arthroscopy follows a structured physical therapy timeline. Gentle jaw exercises begin the same day as surgery, with patients performing simple range-of-motion movements about 20 times each, three times a day. Within the first two days, hands-on stretching exercises are added. More advanced exercises are introduced over the following two to three weeks. You’ll likely be on a soft diet for one to two months, and the overall goal is to restore functional jaw movement within that same timeframe.
Choosing the Right Surgeon
Because TMJ surgery is relatively uncommon compared to procedures like wisdom tooth extraction, not every oral surgeon performs it regularly. When you meet with a potential surgeon, the American Board of Oral and Maxillofacial Surgery suggests asking how frequently they perform the specific procedure, what the most common complications are at their practice, what steps they take to prevent those complications, and how they handle problems if they arise. A surgeon who does several TMJ procedures a month is in a very different position than one who does a few per year.
Board certification through ABOMS is one useful marker of training and competency, but it doesn’t guarantee TMJ-specific expertise. Look for a surgeon whose practice emphasizes temporomandibular joint disorders, and don’t hesitate to seek a second opinion if the recommended procedure is an open surgery or total joint replacement.
