Jaw Clicking When Chewing: Causes and Fixes

Jaw clicking when chewing usually means the small cartilage disc inside your temporomandibular joint (TMJ) sits slightly forward and snaps back into place as you open and close. Disc displacement shows up in 18% to 35% of the general population, and for most people it stays painless and stable for life. Clicking that comes with pain, catching, or a jaw that locks needs an exam.

What causes jaw clicking when chewing

Jaw clicking when chewing happens when the disc that cushions your jaw joint sits ahead of where it belongs, so the rounded end of the jawbone has to pop over it every time you open and close.

You have two temporomandibular joints, one in front of each ear. Each one has a small disc of cartilage between the jawbone and the skull. When the disc stays centered, the jaw glides without a sound.

When the disc slides forward, the jawbone catches its back edge on the way open and slips past it with a click. Dentists call this disc displacement with reduction, and it is the most common reason a jaw clicks.

Several things push the disc forward or keep it there:

• Clenching and grinding (bruxism). Hours of pressure at night overload the joint and the muscles around it.
• A bite that does not meet evenly. When one tooth hits early, the jaw shifts to get around it, and the joint on that side takes the strain.
• Arthritis. Wear in the joint surface changes how the disc tracks.
• An old injury. A blow to the chin or a hard fall can stretch the ligaments that hold the disc.
• Daily habits. Gum, nail biting, chewing ice, and biting into tall sandwiches all stretch the joint past its comfortable range.

Not every jaw sound means the same thing. Here is how I sort them in the chair.

Is jaw clicking when chewing normal

Painless jaw clicking is common, and the National Institute of Dental and Craniofacial Research considers it normal and not something that requires treatment.

The numbers back that up. A systematic review of 167 papers in the Journal of Oral Rehabilitation found disc displacement in 18% to 35% of the general population. The authors described it as a stable, pain-free, lifelong condition for most people, and they called it a “noisy annoyance” rather than a disease.

Only a small minority of people with a clicking disc go on to lose the click because the disc stops slipping back. Even then, the same review found that a painful, limited mouth opening is rare, and when it does happen, the symptoms tend to improve and often resolve within months.

That is the short version I give patients who come in worried: the click by itself is not the problem.

The bigger picture is TMD, the family of jaw joint and jaw muscle disorders. TMD affects about 5% of adults in the United States, and it is twice as common in women, especially between ages 35 and 44. A click can be one sign of TMD, but a click alone does not make the diagnosis.

Why does my jaw click on one side only?

One-sided jaw clicking means the disc on that side has shifted while the other side still tracks normally.

Both joints move together because they share one bone, so anything that loads one side more than the other can shift one disc. I see it most with chewing on one side, often because a tooth on the other side is sensitive or missing. I also see it with sleeping face down on one side, with one-sided clenching, and with a filling or crown that sits a little high and makes the jaw swing around it.

A click on one side with no pain gets the same answer as any painless click. Leave it alone and keep an eye on it. If that side starts to ache, or you notice your jaw swings toward the clicking side when you open, that is the time to have the bite checked.

How to stop jaw clicking when chewing

You stop jaw clicking by taking load off the joint and retraining the muscles that move it, and for most people that means soft foods, jaw rest, warmth, and daily coordination exercises for two to three weeks.

The evidence for this kind of self-care is decent and improving. A 2026 umbrella review of 11 systematic reviews, covering 49 primary studies, concluded that patient education, behavior change, and jaw exercises reduce pain and improve jaw movement in people with TMD. The authors rated the certainty of that evidence as low to very low, so I present it as the best starting point, and it is also the safest one.

Here is the routine I give patients.

• Rest the joint. Switch to softer foods, cut food small, and skip gum and ice. When you yawn, put a fist under your chin so the jaw cannot drop wide open.
• Reset your resting position. Lips together, teeth slightly apart, tongue resting on the roof of your mouth. Your jaw muscles cannot clench with your tongue up there.
• Use warmth. A warm compress on the side of the face relaxes the chewing muscles. If the joint feels hot or swollen, use cold instead.
• Retrain the movement. The TMJ exercises I give my patients teach the opening muscles to lead the movement so the joint tracks straight. Give them three weeks.
• Catch daytime clenching. Set a phone reminder a few times a day and check whether your teeth are touching. They should not be.
• Protect the joint at night. If you grind, a custom guard spreads the force so the disc is not crushed for seven hours. NIDCR notes that splints have limited evidence for TMD pain and should never permanently change your bite, which is why I measure and adjust every guard to the bite you already have.

When a patient has done this for three weeks and the click still comes with pain, I look deeper. A TMJ evaluation in Huntersville at my office covers the joints, the chewing muscles, the bite, tooth wear, range of motion, and imaging when it is needed. I screen for airway and stress factors because they drive clenching, and when a case involves advanced joint damage I refer to an oral surgeon or TMJ specialist instead of guessing.

One rule I hold to is that I treat pain, limited opening, and a bite that is wearing the joint down, and a sound on its own stays on the watch list.

When jaw clicking needs a dentist

Jaw clicking needs a dentist when it comes with pain, when the jaw catches or locks, or when your mouth opens less than it used to.

“I think if it’s painful, it should definitely be addressed,” says Dr. Gary Lowder, DDS, a professor at the University of Utah School of Dentistry with three decades of TMJ experience. I agree, and I add two more triggers: locking and a change in opening.

An exam does not make sense when the click is painless, your mouth opens fully, and the sound has not changed in years. I tell those patients to save their money and come back if anything on the list above shows up.

Common mistakes and myths about jaw clicking

Most of the harm I see from jaw clicking comes from what people try on their own.

• Myth: You can pop the disc back yourself. The disc is held by ligaments and a muscle. Pushing on your chin or wiggling your jaw does not move it, and forcing it can inflame the joint.
• Myth: Every click turns into a locked jaw. The Journal of Oral Rehabilitation review found the opposite. Most clicking discs stay exactly as they are for life.
• Mistake: Chewing gum to “strengthen” the joint. Gum keeps the disc under constant load. It is the single habit I ask patients to drop first.
• Mistake: Opening wide on purpose to “click it through.” Each forced pop stretches the ligament that is already loose.
• Myth: Surgery fixes a click. NIDCR and every TMJ guideline I follow put conservative care first, because surgery makes permanent changes to the joint and a painless click does not justify that.
• Mistake: Ignoring the ear. Jaw joint pain refers to the ear so often that patients see a physician for an ear infection first. If your ear hurts and your hearing is fine, mention the jaw.

What if my click is different

What if my jaw clicks only when I yawn wide?

That pop at full stretch usually comes from the jawbone sliding past the front of its socket, and the disc has nothing to do with it. It is common and rarely needs treatment. Support your chin when you yawn, and it will mostly disappear.

What if my jaw used to click and now it does not, but it feels tight?

The disc may have stopped slipping back into place. For most people, this is uneventful, but if your opening has dropped or the joint aches, book an exam within a week or two so we can get it moving while it is easy to treat.

What if the click started after a long dental appointment or an injury?

The joint has been stretched. Treat it like a sprained ankle: soft foods, warmth, no wide opening, and two to three weeks of patience. If pain climbs instead of settling, come in.

What if I am also waking up with headaches?

Morning headaches over the temples point to night clenching, and the click is a side effect of that load. The guard and the resting-position habits above matter more than anything aimed at the click itself.

Frequently asked questions

How do I get my jaw to stop clicking?

Take load off the joint for two to three weeks: soft foods, no gum, no wide yawns, warmth on the muscles, and daily coordination exercises. Keep your lips together and teeth apart during the day. If the click is painless it may never fully stop, and that is fine. If it hurts after three weeks, see a dentist.

Is it normal for my jaw to click every time I chew?

Yes, when it does not hurt and your mouth opens fully. Disc displacement with reduction affects 18% to 35% of people and is stable and painless for most of them for life. A click that comes with pain, catching, locking, or a smaller opening is the version that needs an exam.

What is the 3-finger test for TMJ?

Stack your index, middle, and ring fingers and try to fit them vertically between your front teeth. Most adults can, which lines up with an average adult mouth opening of about 49 mm; under 40 mm is generally treated as limited. If three fingers will not fit, or opening that far hurts, a dentist should measure it.

How do I reset my TMJ jaw?

You cannot manually reset the disc, and forcing the jaw can make it worse. What resets the joint is rest and retraining: soft foods, warmth, tongue on the roof of your mouth with teeth apart, and coordination exercises for three weeks. If the jaw is locked open or closed, do not push it. Call a dentist the same day.

Why does my jaw click when chewing but it does not hurt?

A painless click means the disc slips forward and snaps back without irritating the joint. NIDCR considers that normal and does not advise treatment. Your job is to keep it that way: skip gum, avoid wide bites, and watch for pain or catching. If neither shows up, the click is a sound and nothing more.

What to do next

If your click is painless and your mouth opens fully, start the two-to-three-week self-care routine above and watch for changes.

If the click comes with pain, catching, or a smaller opening, book a TMJ evaluation. I will check the joints, the chewing muscles, the bite, and your range of motion, and I will tell you at the first visit whether this is something I treat or something a specialist should see. The answer for whether TMJ can be cured permanently depends on what is driving yours, and that starts with a diagnosis.
