Bottom line: TMJ treatment costs range from $300–$600 for a custom night guard to $50,000+ for joint replacement surgery. Most TMJ cases are successfully managed with conservative, lower-cost treatments. Insurance coverage varies — some costs fall under dental, others under medical.
TMJ treatment cost by type
| Treatment | Best for | Cost range |
|---|
| Custom night guard (occlusal splint) | Clenching, bruxism, mild TMJ | $300–$700 |
| Physical therapy | Jaw muscle tension, limited opening | $75–$150 per session |
| Botox (masseter injection) | Jaw clenching, muscle pain | $500–$1,500 per treatment |
| Arthrocentesis (lavage) | Locked jaw, joint fluid issues | $500–$1,500 |
| TMJ arthroscopy | Disk displacement, scar tissue | $5,000–$10,000 |
| Open joint surgery | Severe structural damage | $15,000–$50,000+ |
What causes TMJ disorder?
TMJ (temporomandibular joint) disorder encompasses a range of conditions affecting the jaw joint and surrounding muscles. Common causes include teeth grinding (bruxism), jaw injury, arthritis, stress-related muscle tension, and bite misalignment — including untreated overbites and underbites.
Does insurance cover TMJ treatment?
Coverage is inconsistent and depends on how the claim is submitted. Night guards billed as dental appliances are typically covered at 50% under dental insurance. Physical therapy may be covered under medical insurance. Surgery is often covered by medical insurance when deemed medically necessary. Botox for TMJ is hit-or-miss — some medical plans cover it, many don't.
Should I start with conservative treatment?
Yes — always. The American Association of Oral and Maxillofacial Surgeons recommends starting with reversible, non-surgical treatments: jaw exercises, soft diet, anti-inflammatories, a night guard, and stress management. Most patients (75%+) improve significantly with conservative care. Surgery is reserved for cases that don't respond after 6–12 months of conservative treatment.
Frequently asked questions
Is a night guard worth the cost for TMJ? +
For most patients with TMJ caused by clenching or bruxism, yes. A custom night guard ($300–$700) relieves jaw muscle tension, protects tooth enamel, and reduces headaches and jaw pain. OTC night guards ($20–$60) are a less effective but affordable starting point.
Does Botox really work for TMJ? +
Yes — masseter Botox is effective for TMJ pain caused by jaw clenching. Injecting the masseter muscle temporarily reduces its ability to generate forceful clenching, relieving pain and headaches. Results last 3–6 months and the treatment needs to be repeated. It's particularly effective for patients who clench during the day rather than only at night.
Can a bad bite cause TMJ? +
Yes — significant bite misalignment (malocclusion) can contribute to TMJ disorder by placing uneven stress on the joint. Correcting the underlying bite problem through orthodontics or dental work can resolve TMJ symptoms in some patients. However, bite correction is rarely the first-line treatment for TMJ.
