| Self-care and physical therapy | Soft foods, heat or cold, NSAIDs, jaw habit changes, manual therapy | Nearly always first | Yes |
| --- | --- | --- | --- |
| Splints and night guards | Removable appliances that cover the teeth without changing the bite | Clenching, grinding, ongoing muscle pain | Yes |
| Arthrocentesis | Needles flush fluid through the joint to clear adhesions | Disc out of place, pain, limited opening | Yes |
| Arthroscopy | Small camera and instruments placed inside the joint | Adhesions or a displaced disc | Fewer risks than open surgery |
| Open surgery | Incision near the ear for direct repair of the joint | Joint destruction, or severe symptoms despite other treatment | No |
| TMJ replacement | Two FDA-approved implants replace all or part of the joint | Injury, congenital conditions, ankylosis, severe damage after simpler care fails | No |

## Steps to take if surgery is being discussed

1. Ask why surgery is being suggested, what alternatives exist, how the procedure would help your specific problem, and what the risks are, in detail and in plain language.
2. Confirm that reversible treatments have been tried and given enough time, since NIDCR specifically recommends asking about simpler treatments first and trying them.
3. Verify the diagnosis with an examination and, if the picture is unclear or conservative care has failed, appropriate imaging such as MRI or cone-beam CT.
4. Get a second opinion from a qualified medical or dental specialist; NIDCR suggests considering an orofacial pain provider, a field recognized as a dental specialty.
5. Ask about recovery, follow-up, and what happens if the outcome disappoints. Our page on TMJ surgery recovery shows what that period typically involves.

## Red flags that need prompt care, not a wait-and-see plan

Some jaw symptoms need medical attention right away. Contact a clinician promptly, or seek emergency care, if your jaw locks so you cannot open or close it, if you have facial swelling with fever, if you notice facial numbness, or if jaw pain follows an injury to the head or jaw. Severe fever, chills, and difficulty opening the jaw can signal infection in the joint region, and chest pain with jaw pain is an emergency concern. MedlinePlus advises contacting a provider right away if you are having trouble eating or opening your mouth.

## Frequently Asked Questions

### How long should I try other treatments before considering TMJ surgery?

NIDCR recommends trying reversible care first, and many symptoms resolve without treatment. The AAFP review describes a common referral point: severe pain or joint dysfunction that persists beyond three to six months, or a TMJ fracture from trauma.

### Do TMJ problems ever go away completely?

There is no single cure for TMDs. Many episodes improve on their own or with simple care, and chronic cases are usually managed rather than eliminated. Reducing triggers such as clenching and gum chewing often reduces flares over time.

### Is arthroscopy safer than open TMJ surgery?

Mayo Clinic states that TMJ arthroscopy has fewer risks and complications than open-joint surgery. NIDCR says arthroscopy works moderately well for pain and function, while open surgery has no long-term studies on safety or symptom relief.

### Who performs TMJ surgery?

Procedures on the jaw joint are typically performed by an oral and maxillofacial surgeon, a dental specialty recognized in the United States. Nonsurgical care is often managed by a dentist, a physician, or a clinician focused on orofacial pain. If surgery is on the table, [browse TMJ surgeons near you](https://tmjspecialistguide.com/tmj-surgeon-near-me).

### Will insurance cover TMJ surgery?

Coverage varies by plan and is often reviewed case by case, so documentation of diagnosis and failed conservative care matters. Many plans also separate dental benefits from medical benefits, which affects how a claim is handled. Ask your insurer what they need before the procedure; see [our cost of TMJ surgery](https://tmjspecialistguide.com/cost/tmj-surgery) and [providers that accept insurance](https://tmjspecialistguide.com/tmj-insurance).

### Can TMJ surgery make pain worse?

It can. The AAFP review points to a high failure rate and the possibility of worse pain and dysfunction, and MedlinePlus notes results are often worse than before surgery. That is a major reason reversible treatments come first.

### Will I need an MRI before surgery?

Imaging is recommended when the diagnosis is in doubt or conservative treatment is not working, per the AAFP review. MRI is preferred for soft-tissue problems such as disc displacement, while cone-beam CT shows bone changes more clearly.
