What Is TMJ?
Edited by Merve Aydin, Health Content Editor · About 7 min read · General information, not medical advice
| Painless click or pop | Common and usually normal | No treatment unless pain or locking develops |
|---|---|---|
| Painful click, pop, or grating | Possible disk or joint problem | Ask a dentist or clinician to check it |
| Jaw locks open or shut | Possible dislocation or muscle spasm | Seek prompt medical or dental care |
| Aching jaw with morning headache | May reflect clenching or grinding | Discuss habits and a mouth guard with a clinician |
| Facial swelling with fever | Not typical of TMD | Seek urgent medical care |
Other signs include pain that spreads to the face or neck, jaw stiffness, limited opening, and a change in how the upper and lower teeth fit (NIDCR). AAFP notes that opening less than 30 to 35 mm is considered abnormal. TMJ symptoms covers ear, headache, and neck symptoms in more detail.
How Is TMJ Diagnosed?
There is no single standard test for TMD (NIDCR). A clinician will ask about your pain, when it occurs, what makes it better or worse, and whether it spreads. They will examine your head, neck, face, and jaw for tenderness, clicking, and limited movement.
Imaging may be used if the diagnosis is unclear. AAFP says MRI is preferred for soft-tissue problems such as disk displacement, while cone-beam CT is preferred for bony changes. Blood tests are not routinely recommended. How TMJ is diagnosed describes the exam in more detail.
What Helps TMJ Jaw Pain?
Many people improve with simple care. NIDCR says TMD symptoms go away without treatment for many people, and conservative options are recommended first. Self-care may include soft foods, heat or cold, gentle stretches, over-the-counter NSAIDs, and reducing clenching, gum chewing, and nail biting.
NHS suggests an ice pack wrapped in a towel for no more than 5 minutes at a time, or a hot water bottle wrapped in a towel for 15 to 20 minutes twice a day. Stop if either makes the pain worse.
Physical therapy can help some people. NIDCR notes that research suggests manual therapy can improve function and relieve pain. TMJ exercises describes gentle routines, and TMJ physical therapy explains what a session may involve.
A clinician may also discuss a splint or mouth guard, medications, trigger point injections, arthrocentesis, arthroscopy, or surgery. Evidence for many treatments is limited, and NIDCR advises trying simpler options before anything irreversible. A splint should not be designed to permanently change your bite. Botulinum toxin is not FDA-approved for TMD, and study results are mixed (NIDCR). For a broader look, see TMJ treatment options.
If you are not sure where to start, these steps can help:
- Keep a short log of when the pain starts, what you were doing, and what eases it.
- Choose soft foods for a few days and avoid gum, hard candy, and nail biting.
- Try a wrapped ice pack or heat pack using the time limits above, and stop if pain increases.
- Notice clenching during the day and rest your tongue on the roof of your mouth with your teeth apart.
- Book a visit with a dentist or physician if pain lasts, returns often, or limits opening.
- Seek urgent care for a jaw locked open or shut, facial swelling with fever, numbness, jaw pain with chest pain or shortness of breath, or after a hard blow to the face.
Who Can Help With TMJ Jaw Pain?
Several clinicians may be involved. A dentist can check the teeth, bite, and signs of grinding. A physician can look for other causes and manage medications. A physical therapist can assess posture, neck, and jaw movement. Oral and maxillofacial surgery is a recognized dental specialty, and a surgeon in that field may be consulted for severe joint problems or surgery.
Orofacial Pain is one of the 12 dental specialties recognized by the National Commission on Recognition of Dental Specialties and Certifying Boards. That recognition describes a field of practice; it does not tell you about an individual clinician's training or experience.
When you call, ask what the clinician treats most often, whether they treat jaw pain regularly, and what imaging or referral options they have. To find care, use TMJ doctor near you or orofacial pain provider near you.
Frequently Asked Questions
Is TMJ the same as TMD?
Not exactly. TMJ is the name of the joint, while TMD is the term for disorders of the joint and the chewing muscles. Many people say "TMJ" when they mean TMD, and clinicians usually understand the shorthand.
What does TMJ jaw pain feel like?
It may feel like an ache in the jaw, face, or ear, or like soreness when you chew or yawn. Some people notice clicking, stiffness, or a tired feeling in the jaw. Pain can be one-sided or on both sides.
Can TMJ go away on its own?
Often, yes. NIDCR says many TMDs last only a short time and go away without treatment. Cleveland Clinic notes that some people feel better in a week or two, while others need ongoing care.
What should I do first for TMJ jaw pain?
Start with simple measures such as soft foods, a break from chewing gum, and short applications of heat or cold. Notice clenching habits and avoid opening your mouth too wide. If pain persists or limits movement, ask a dentist or physician to evaluate it.
When is TMJ an emergency?
Get urgent help if your jaw is locked open or shut, if you have facial swelling with fever, numbness, or a hard blow to the face, or if jaw pain comes with chest pain or shortness of breath. Those signs may point to a problem that needs prompt treatment.
Does a night guard fix TMJ?
A night guard or splint may help some people, but evidence is limited. NIDCR says there is not a lot of evidence that intraoral appliances improve TMD pain. A device should not be designed to permanently change your bite, and you should stop using it if it causes pain.
