TMJ Symptoms: Causes and Relief Options

TMJ symptoms — jaw pain, clicking, stiffness, or trouble opening your mouth all the way — are more common than most people realize, and they tend to get more attention as we get older and notice new aches that didn’t used to be there. The temporomandibular joints (TMJs) are the two hinge joints connecting your jawbone to your skull, one in front of each ear, and when something goes wrong with them or the muscles that control them, doctors call it a temporomandibular disorder, or TMD. Here’s what the symptoms actually look like, what tends to cause them, and — just as important — why experts recommend starting with the simplest treatments first.

What Is TMD, and How Is It Different From “TMJ”?

Strictly speaking, “TMJ” refers to the temporomandibular joint itself — the hinge joint on each side of your jaw — while “TMD” (temporomandibular disorders) refers to the actual conditions that affect it. In everyday conversation, most people use “TMJ” to mean the disorder, and that’s fine, but it helps to know the distinction when you’re reading medical information. The NIDCR describes TMDs as a group of more than 30 different conditions that fall into three broad categories: disorders of the joint itself (including disc problems), disorders of the chewing muscles, and headaches associated with a TMD.

Many cases of TMD are short-lived and resolve on their own without any specific treatment. In some people, though, symptoms become chronic, or long-lasting, and TMD can sometimes occur alongside other conditions like headaches, back pain, sleep problems, irritable bowel syndrome, and fibromyalgia, according to the NIDCR.

Common TMJ Symptoms

According to the NIDCR, the symptoms that may signal a TMD include:

• Pain in the chewing muscles and/or the jaw joint itself — this is the most common symptom
• Pain that spreads to the face or neck
• Jaw stiffness
• Limited jaw movement, or the jaw locking in an open or closed position
• Painful clicking, popping, or grating sounds in the jaw joint when opening or closing the mouth
• Ringing in the ears, hearing loss, or dizziness
• A change in the way the upper and lower teeth fit together

One important clarification from the NIDCR: clicking or popping sounds in the jaw joint, without pain, are common and considered normal — they don’t require treatment on their own. It’s pain and functional problems like stiffness, locking, or a change in your bite that are the signals worth paying attention to.

What Causes TMD?

Here’s something that may be surprising: in most cases, the exact cause of TMD isn’t clear. The NIDCR is direct about this, noting that while injury to the jaw joint can lead to some TMDs, for many people symptoms simply start without an obvious reason. Current research suggests that a combination of genetics, psychological and life stressors, and how an individual perceives and processes pain may all play a role in whether someone develops TMD and whether it becomes a long-lasting problem.

It’s also worth correcting a couple of common assumptions. The NIDCR specifically notes that research does not support the once-common belief that a “bad bite” or orthodontic treatment, like braces, causes TMD. Researchers are still exploring whether structural differences in jaw joint anatomy between women and men play a role in why TMD is more common in women, but no firm conclusion has been reached.

Who Gets TMD?

According to the NIDCR, TMD affects about 5% of adults in the United States, though that figure can vary depending on how a particular study defines and measures the condition. TMDs are roughly twice as common in women as in men, and the gap is most pronounced in women between the ages of 35 and 44. That age range overlaps with the years leading into the 50+ window many of our readers are in, which is part of why TMJ-related pain and jaw stiffness can feel like they show up, or worsen, as people move through their 40s, 50s, and beyond.

How TMD Is Diagnosed

There’s no single standard test for diagnosing TMD, which the NIDCR says is part of what makes diagnosis challenging — the causes vary, and the symptoms overlap with other conditions. A doctor or dentist will typically start by taking a detailed history, asking where the pain is located, when it happens, what makes it better or worse, and whether it spreads to other areas. They’ll usually examine your head, neck, face, and jaw for tenderness, check for clicking or popping, and assess how well your jaw moves. Depending on what they find, imaging such as an x-ray, MRI, or CT scan may be used to get a clearer picture of the joint, and other conditions with similar symptoms may need to be ruled out first.

Treatment: Start Simple

This is probably the most important thing to know about TMD treatment: because the evidence for many treatments is limited, experts recommend starting with conservative, reversible options and specifically avoiding treatments that permanently change your jaw joint, teeth, or bite unless simpler approaches have genuinely failed. The NIDCR is explicit that signs and symptoms of TMD go away without any treatment for many people, so starting simple isn’t just about caution — it often works.

Initial, low-risk steps recommended by the NIDCR include:

• Eating soft foods to reduce strain on the jaw
• Applying heat or cold to the face, combined with gentle stretching and strengthening exercises for the jaw muscles
• Taking over-the-counter pain relievers, such as NSAIDs like ibuprofen
• Reducing habits that strain the jaw, including clenching, gum chewing, and nail biting

Beyond these first steps, other conservative options have some supporting evidence. Manual physical therapy, in which a therapist uses their hands to stretch and work the soft tissue and muscles around the joint, has been shown in research to help improve jaw function and relieve pain. Behavioral approaches, including cognitive behavioral therapy and biofeedback therapy, can also help some people manage TMD, and general self-management strategies — learning about your specific type of TMD, practicing relaxation techniques, and staying engaged in meaningful activities — are part of the NIDCR’s recommended approach.

Intraoral appliances, commonly called night guards or splints, are often suggested by dentists. The NIDCR notes they don’t permanently change your teeth or bite, which is reassuring, but also points out there isn’t a lot of strong evidence that they actually improve TMD pain. If your dentist recommends one, make sure it’s not designed to permanently alter your bite, and stop using it and follow up if it causes you pain.

When More Invasive Treatment Might Be Considered

The NIDCR is notably cautious about treatments that are harder to reverse. Occlusal treatments like grinding down teeth, placing crowns, or orthodontic correction specifically to treat TMD have insufficient evidence of effectiveness and, in some cases, can make symptoms worse. Botulinum toxin injections are FDA-approved for other conditions like migraines but not specifically for TMD, and it remains unclear whether they help. Procedures like prolotherapy and arthrocentesis have limited or inconsistent research behind them.

Surgical options exist for more severe cases — arthroscopy, open joint surgery, and in rare cases, TMJ implants — but the NIDCR specifically recommends these only be considered when there’s joint damage that can’t be addressed another way, or when severe symptoms persist despite trying other treatments. The agency’s own guidance is to ask about simpler treatments first, and to seek a second opinion from a qualified specialist, ideally one focused on orofacial pain, before agreeing to any treatment that permanently changes your jaw, teeth, or bite.

TMD and Headaches

One category the NIDCR specifically calls out is headaches associated with TMD. Jaw muscle tension and joint dysfunction can refer pain to the temples, the sides of the head, and behind the eyes, which means some people experience what feels primarily like a headache disorder without immediately connecting it back to their jaw. If you have recurring headaches along with jaw stiffness, clicking, or soreness — particularly if headaches tend to show up after a stressful day of unconscious clenching, or first thing in the morning after a night of grinding — it’s worth mentioning both symptoms together when you see a doctor or dentist, since treating the underlying jaw issue can sometimes ease the headaches as well.

Self-Care Tips Worth Trying

If you’re dealing with mild to moderate jaw pain or stiffness, a few simple habits can make a real difference while symptoms often resolve on their own. Stick to softer foods for a while rather than chewing tough or crunchy items that strain the jaw. Apply a warm compress to the jaw area to relax tense muscles, or try a cold pack if there’s acute swelling or pain. Be mindful of habits like chewing gum, biting your nails, or clenching your jaw during the day, especially during stressful moments — many people clench without realizing it. If you wake up with jaw soreness, nighttime clenching or grinding (bruxism) may be contributing, and it’s worth mentioning to your dentist, who may suggest a properly fitted night guard.

Frequently Asked Questions

Is jaw clicking always a sign of a problem?

No. According to the NIDCR, clicking or popping sounds in the jaw joint without pain are common, considered normal, and don’t require treatment. It’s when clicking is accompanied by pain, locking, or limited movement that it’s worth mentioning to a doctor or dentist.

Can TMD go away on its own?

Yes, often. The NIDCR notes that many TMD symptoms go away without any specific treatment, and many jaw joint and muscle problems are temporary and don’t worsen over time. That’s part of why conservative, simple treatments are recommended as the starting point rather than more invasive options.

Should I see a dentist or a doctor for TMJ symptoms?

Either can be a reasonable starting point, since diagnosis often involves both dental and medical perspectives. Many people start with their dentist, who can examine the jaw, teeth, and bite and may refer you to an oral and maxillofacial specialist or an orofacial pain specialist if symptoms are persistent or severe.

Does stress really affect TMJ symptoms?

Current research suggests that psychological and life stressors may play a role in both the development of TMD and whether symptoms become long-lasting, according to the NIDCR. Many people also clench or grind their teeth more during stressful periods without realizing it, which can aggravate jaw muscles and contribute to symptoms.

Are night guards effective for TMJ pain?

Night guards, also called intraoral appliances or splints, are commonly recommended and don’t permanently alter your teeth or bite. However, the NIDCR notes there isn’t strong evidence that they reliably improve TMD pain, so results vary from person to person. If one is recommended, make sure it isn’t designed to permanently change your bite, and stop using it if it causes pain.

This article is for general educational purposes and isn’t a substitute for personalized medical advice. If you’re experiencing persistent jaw pain or TMJ symptoms, talk to a dentist or doctor about an evaluation before starting any treatment.

TMJ symptoms are common, often temporary, and in most cases respond well to simple, conservative care rather than anything invasive. If jaw pain, clicking, or stiffness has been bothering you, start with the basics — soft foods, heat or cold, and cutting back on jaw-clenching habits — and loop in your dentist or doctor if things aren’t improving after a few weeks or if the pain is significant.
