Your jaw clicks every time you eat breakfast. A dull ache spreads from your ear to your temple by mid-afternoon. You catch yourself clenching your teeth during work calls. Is this normal, or is it something more?
TMJ disorder affects between 5 and 12 percent of adults in the United States, according to the National Institute of Dental and Craniofacial Research (NIDCR). Women develop TMJ problems at roughly twice the rate of men. Most cases start between age 20 and 40.
The good news: most people improve with non-surgical treatment once they get a proper diagnosis.
Dr. Nina Mojaver, DMD, has treated TMJ and craniofacial pain at San Diego Sleep and TMJ Center for more than 25 years. She sees patients every week who spent months blaming headaches on stress or ear pain on allergies before learning the jaw joint was the real source.
Key takeaways if your jaw hurts
- TMJ disorder affects 5 to 12 percent of U.S. adults. Clicking alone does not always need treatment.
- The six most common signs are jaw pain, clicking, limited movement, headaches, ear pain, and discomfort while chewing.
- Stress, teeth grinding, and bite misalignment are the most frequent causes.
- Most cases respond to non-surgical treatment such as bite correction and custom oral appliances within weeks.
- If jaw pain lasts more than two weeks or disrupts eating or sleep, call San Diego Sleep and TMJ Center at 619-657-0787.
What is TMJ disorder?
TMJ stands for temporomandibular joint. You have one on each side of your face, just in front of your ears. Each joint connects your lower jaw to your skull. It works like a hinge with a sliding motion. You use both joints every time you talk, chew, yawn, or swallow.
TMJ disorder, sometimes called TMD, happens when the joint or the muscles around it stop working correctly. The Cleveland Clinic reports that TMD causes jaw pain, headaches, and trouble chewing. It ranks among the most common sources of chronic facial pain in adults.
A small disc of cartilage inside each joint cushions the bones during movement. When that disc shifts or wears thin, the joint loses its smooth glide. Clicking, locking, and pain often follow.
How do you know if your jaw pain is TMJ?
Six symptoms show up again and again in people with TMJ disorder. Not everyone gets all six. Having two or more of these for longer than two weeks usually warrants a professional look.
Jaw pain or tenderness
Pain near the hinge of the jaw, just in front of the ears, is the most reported symptom. It might feel dull and steady or sharp when you chew. Some people notice it most in the morning. That pattern often points to nighttime teeth grinding.
Clicking, popping, or grinding sounds
A click or pop when you open your mouth usually means the disc inside the joint has slipped. Occasional clicking without pain may not need treatment. Frequent clicking paired with pain or a catching feeling tells you the joint is not tracking right.
Limited jaw movement or locking
Difficulty opening your mouth wide, or a feeling that your jaw stalls before releasing, can point to disc problems or muscle spasm. In more serious cases, the jaw locks open or shut for several seconds. This affects eating, speaking, and even yawning.
Can TMJ disorder cause headaches?
Yes. The muscles that move the jaw attach near the temples and the base of the skull. When those muscles stay tight from clenching or grinding, they send pain upward. Many people treat these headaches as migraines for months before a dentist traces the problem back to the jaw.
Why does TMJ disorder cause ear pain?
The jaw joint sits less than a centimeter from the ear canal. Swelling or tension in the joint area puts pressure on nearby nerves. The result can feel like an earache, ringing, or a plugged sensation in one or both ears.
These symptoms often mimic an ear infection. That is why many people visit their primary care doctor first, only to find out the jaw was the problem all along.
Pain while chewing
Chewing should feel easy. If your jaw tires during meals, or if biting down sends a jolt through the joint, those muscles and the joint are working under strain. Some people drift toward softer foods for weeks before they recognize the pattern.
Why does TMJ disorder happen?
There is rarely a single cause. TMJ disorder usually builds over time from a mix of factors that strain the joint and the surrounding muscles.
Teeth grinding and clenching, called bruxism, top the list. The NIDCR notes that bruxism places repeated force on the joint and wears down the cartilage disc. Many people grind in their sleep. They only find out when a dentist spots worn tooth surfaces or a partner hears the noise at night.
Stress plays a direct role. Anxious people tend to tighten the jaw and clench without knowing it. After days and weeks of constant tension, the muscles grow sore and the joint aches.
Bite problems force the jaw into positions it was not built for. When upper and lower teeth do not meet evenly, the muscles pull the joint off track to compensate. This is why a dentist who understands jaw mechanics often identifies TMJ disorder faster than a general physician.
Other factors include arthritis, a blow or injury to the jaw, and posture habits that shift head and neck alignment.
Can TMJ disorder get worse if you ignore it?
Mild TMJ symptoms sometimes go away on their own within a few weeks. The Mayo Clinic notes that most TMJ discomfort lasts a limited time and responds well to self-care. But not every case stays mild, and the consequences of waiting depend on what is causing the problem.
Ongoing grinding wears down tooth enamel and can crack teeth. Chronic muscle tension around the joint can turn into a daily headache cycle that grows harder to break with time. A displaced disc that goes unaddressed can let the joint bones rub together, and that contact leads to changes that are tougher to treat later.
Here is the practical rule: if jaw pain has lasted more than two weeks, wakes you at night, or makes eating difficult, waiting raises your risk more than it lowers it.
How do TMJ treatments work?
Most TMJ disorders respond to non-surgical care. Surgery applies only to structural joint damage that has not improved after conservative steps.
Bite evaluation and correction
A dentist trained in jaw mechanics checks how the upper and lower teeth meet. In many cases, TMJ symptoms trace back to overworked muscles that compensate for an uneven bite. Correcting the bite relieves that strain. At San Diego Sleep and TMJ Center, this evaluation takes about half an hour and does not require surgery.
Custom oral appliances
A custom-fitted splint or night guard keeps the teeth apart during sleep and holds the jaw where it puts the least pressure on the joint. Over-the-counter guards cushion teeth but do not correct bite mechanics. A dentist-supervised appliance repositions the jaw, not just protects the enamel.
Supportive therapies
Physical therapy exercises for the jaw improve range of motion and ease tightness. Anti-inflammatory drugs help with flare-ups. In stubborn cases, targeted Botox injections into the masseter muscle reduce clenching force and provide months of relief.
What can you do at home right now?
While you wait for a professional evaluation, a few changes can take pressure off your jaw right away.
Stick to softer foods for a week or two. Skip chewing gum, hard apples, and jerky. Cut food into smaller pieces so your jaw does not have to open as wide.
Place a warm, damp cloth on the sore side of your jaw for 10 to 15 minutes before bed. Moist heat loosens tight muscles and can cut down morning stiffness.
Watch for daytime clenching. Set a phone reminder every two hours: are your teeth touching? At rest, your lips can stay closed but your teeth should sit slightly apart. That alone removes a surprising amount of strain.
When you yawn, support your chin with a hand. Take smaller bites during meals. These small daily shifts add up.
TMJ evaluation in Downtown San Diego
If the signs listed here match what you feel, the most useful next step is a clear diagnosis. A TMJ evaluation covers the jaw joint, the bite, and the muscles of the face, head, and neck. The goal is to find what is driving the pain and build a treatment plan around it.
TMJ disorder also shares risk factors with sleep apnea, so a practice that understands both conditions can catch problems a single-focus office might miss.
Dr. Mojaver and Dr. Pavlisin, DDS, bring a combined 65 years of focus on TMJ and orofacial pain. San Diego Sleep and TMJ Center sits at 450 A Street, Suite 400, in downtown San Diego. The office serves patients throughout the San Diego metro area, Monday through Friday.
