TMJ Botox
Edited by Merve Aydin, Health Content Editor · About 7 min read · General information, not medical advice
| Masseter | Side of the jaw, near the angle and lower cheek | A strong jaw-closing muscle; muscle pain and grinding effects | Cleveland Clinic describes Botox as a supplemental therapy to relax strong masseter muscles. |
|---|---|---|---|
| Temporalis | Temple, above and beside the ear | Jaw-closing activity and temple pain; often treated with the masseter | In one study, each muscle received three sites about 1 cm apart. |
| Lateral pterygoid | Deep in the face, behind the upper jaw | Jaw opening and disc position in some protocols | Hard to reach; one pilot used one extraoral and one intraoral point per side. |
| TMJ itself | The jaw joint, just in front of the ear | Joint-related symptoms in some studies | This is a joint injection, not a muscle injection, and evidence for joint disease is limited. |
How clinicians choose and place the injections
A cosmetic frown line has a predictable target. Jaw pain does not. A clinician first checks which muscles are tender, overactive, or enlarged, then decides what to treat. Cleveland Clinic notes that therapeutic jaw injections need more precision than cosmetic ones and should be given by an oral surgeon, an otolaryngologist (ENT), or an experienced plastic surgeon.
A typical visit may follow these steps:
- Review your symptoms, medical history, and treatments you have already tried.
- Examine your jaw, face, and neck, including how wide you can open.
- Ask you to clench so the chewing muscles stand out.
- Mark the selected sites and clean the skin.
- Inject the chosen muscles, then schedule a follow-up to judge the response.
The number of sites varies with the protocol and your anatomy. One study used three points in each masseter and temporalis; the 20-person pilot used eight points on one side.
What the evidence says about TMJ Botox
NIDCR states that botulinum toxin type A is FDA-approved for some conditions, such as migraines, but not for TMDs. Studies have looked at it for TMDs, but results are mixed, and it remains unclear whether it relieves symptoms. Cleveland Clinic makes the same point and adds that some studies suggest a better result for teeth grinding than for pain.
The AAFP rapid evidence review reports that one systematic review found intramuscular onabotulinumtoxinA decreased myalgias but not arthralgias. Mayo Clinic describes jaw-muscle botulinum toxin as a rarely used option that may ease pain related to TMJ disorders.
Small studies are not proof. The 20-person pilot reported improvements in mouth opening and chewing pain at six weeks, but it was uncontrolled and preliminary. The 21-patient study reported changes before and after treatment rather than comparing two treatments. For context, TMD affects about 5% of U.S. adults, and the category includes more than 30 conditions, according to NIDCR. Injections are usually considered after simpler care, not instead of it.
TMJ Botox side effects and safety
Cleveland Clinic lists injection-site pain, bruising, swelling, and redness; unwanted facial paralysis or cosmetic changes such as a drooping eyelid or uneven smile; infection or allergic reaction; headache and neck pain; flu-like symptoms; nausea or indigestion; and muscle weakness. Serious harm from legitimate, properly prepared Botox is extremely rare. Cleveland Clinic notes that the last recorded case of botulism from a therapeutic injection was in 2017. Counterfeit products are a separate risk, and the CDC issued an alert about them in April 2024.
Seek urgent medical care for a jaw locked shut or wide open, facial swelling with fever, numbness, recent trauma, or chest pain with jaw pain. Those symptoms need evaluation beyond a cosmetic or dental visit.
Who provides TMJ Botox, and what to ask
Providers who treat TMD include dentists, orofacial pain providers, oral and maxillofacial surgeons, ENTs, and physical therapists. Not every clinician who offers Botox for wrinkles is set up for jaw injections. Ask who will perform the injection, what training they have, whether the product is genuine and stored properly, and what follow-up is included. You can compare TMJ doctors near you and orofacial pain providers near you, or read when to get TMJ Botox.
Cost and coverage
Cost depends on the provider, the number of units, the number of sites, and whether the visit is billed as medical or dental. Insurance often separates dental and medical benefits, so ask for the billing code and a written estimate before treatment. See TMJ Botox cost and whether insurance covers TMJ Botox. Comparing TMJ treatment options and TMJ Botox before and after can help you judge whether injections are worth the out-of-pocket cost.
Frequently Asked Questions
What are the usual TMJ Botox injection sites?
The masseter and temporalis are the muscles commonly treated. Some clinicians also inject the lateral pterygoid, and a few protocols include the TMJ itself. The choice depends on which structures are causing symptoms.
How many injections will I need?
It varies. One study used three sites in each masseter and temporalis, while a small pilot used eight total points on one side. Your clinician will base the number on how many muscles are involved and the product used.
Do TMJ Botox injections hurt?
You may feel a brief pinch and some pressure. Cleveland Clinic lists injection-site pain, bruising, and swelling as possible afterward. Ask about numbing or aftercare if needle discomfort worries you.
How long do TMJ Botox injections last?
Cleveland Clinic says effects often last about three or four months, though severe pain or very strong jaw muscles may mean more frequent treatment. Some people notice a change within a day, while others wait a couple of weeks.
What are the TMJ Botox side effects?
Common ones include bruising, swelling, headache, and muscle weakness. Unwanted facial weakness or a changed smile is possible and should be discussed before treatment. Seek urgent care for severe muscle weakness or trouble breathing.
Is TMJ Botox FDA-approved?
No. The FDA has not approved botulinum toxin for TMD, though it is approved for some other medical uses such as migraines. That is why clinicians usually consider it only after more conservative care.
Can a dentist give TMJ Botox?
Some dentists offer it, but training and office setup vary. Ask who performs the injection, whether the product is legitimate and properly stored, and what follow-up is included.
