Jaw popping happens when a small disc of cartilage inside your jaw joint slips out of its normal position and then snaps back into place as you open or close your mouth. About 5% of U.S. adults experience jaw joint problems, and women are roughly twice as likely to be affected as men. The good news: most jaw popping responds well to a combination of home care, habit changes, and, when needed, professional treatment.
Why Your Jaw Pops
Your jaw joint (the temporomandibular joint, or TMJ) works like a hinge with a sliding component. A small, rubbery disc sits between your skull and jawbone, cushioning the movement. When that disc shifts forward, it can get caught during opening and then pop back into place, producing an audible click. This is called disc displacement with reduction, and it’s the most common cause of jaw clicking.
The disc can shift for several reasons: habitual clenching or grinding (bruxism), a blow to the face, chewing heavily on one side, or simply joint laxity you were born with. Stress plays a major role because it drives unconscious clenching during the day and grinding at night, both of which overload the joint and surrounding muscles.
Home Strategies That Help
Rest Your Jaw
Think of a popping jaw like a sore knee: the less unnecessary load you put on it, the faster it calms down. Avoid wide yawning, gum chewing, biting into apples or bagels, and resting your chin on your hand. When you yawn, support your jaw by pressing a fist gently under your chin to limit how far it drops.
Switch to Softer Foods
During a flare, a soft-food diet for one to two weeks can make a noticeable difference. Good options include bananas, cooked vegetables (peeled carrots, squash, peas), scrambled eggs, fish, yogurt, and pasta. Avoid tough or chewy proteins like steak and jerky. Cut food into small pieces so you don’t have to open wide, and chew evenly on both sides.
Use Heat and Ice
For the first three days of increased pain or popping, apply an ice pack wrapped in a cloth to the side of your jaw for 15 minutes, three to four times a day. After those initial three days, switch to moist heat (a warm, damp washcloth, no hotter than bath water) on the same schedule for about a week. If one approach alone isn’t enough, alternate five to eight minutes of moist heat with five to eight minutes of ice in the same session.
Check Your Sleep Position
Sleeping on your stomach presses one side of your jaw into the pillow and pushes the joint out of alignment. Sleeping flat on your back can also increase jaw muscle tension. Side sleeping tends to relieve pressure on the joint best. If you’re a back sleeper, propping yourself up slightly with pillows to create a gentle incline can reduce some of that pressure.
Exercises and Relaxation Techniques
Gentle jaw exercises can retrain the muscles that guide the disc. One of the simplest: place the tip of your tongue on the roof of your mouth just behind your upper front teeth, then slowly open and close your jaw. The tongue position encourages the jaw to track straight rather than deviating to the side where the pop occurs. Do this 10 times, a few times a day.
Controlled opening exercises also help. Place your thumb under your chin and open your mouth slowly against light resistance from your thumb. Hold for five seconds at the widest comfortable point, then close. This strengthens the muscles that stabilize the disc. Lateral movements work too: slide your jaw to the left and right against gentle finger pressure on each side, holding for five seconds per direction.
Because stress-driven clenching is one of the biggest contributors, learning to keep your jaw in a relaxed “rest position” throughout the day matters. Your teeth should not be touching when your mouth is closed. Lips together, teeth apart, tongue resting lightly on the roof of the mouth. Setting periodic reminders on your phone to check your jaw tension can help you build this habit.
Night Guards and Splints
If you grind your teeth at night, a dental splint (often called a night guard) reduces the force on the joint while you sleep. Both hard and soft versions improve jaw symptoms, but research comparing the two found that soft splints produced earlier relief. In one clinical trial, muscle tenderness in the jaw and neck disappeared by three months with a soft splint, compared to four months with a hard one. Soft splints also led to greater mouth-opening range at the four-month mark.
Custom-fitted splints from a dentist outperform the boil-and-bite versions sold in drugstores because they distribute bite forces evenly. Over-the-counter guards can sometimes shift bite alignment and make clicking worse. If cost is a concern, ask your dentist whether your insurance covers a custom appliance for a diagnosed jaw disorder.
Biofeedback for Daytime Clenching
Biofeedback devices, sometimes built into a dental splint, detect when your jaw muscles clench and send a small signal (a vibration or tone) to remind you to relax. This approach is mainly used during waking hours. In a randomized controlled trial, patients using biofeedback splints had significant reductions in both the frequency and duration of clenching episodes, along with less facial muscle pain and improved overall well-being. Even after treatment stopped, the improvements in clenching duration persisted, suggesting the technique helps retrain the habit long-term.
Professional Treatments
Botulinum Toxin Injections
When clenching and muscle tension are severe, injections of botulinum toxin (commonly known by the brand name Botox) into the jaw muscles can weaken them just enough to reduce the grinding force. A typical treatment involves 25 to 50 units in each masseter (the large muscle at the angle of the jaw) and 10 to 25 units in each temporalis muscle at the temple. Relief generally lasts around 12 weeks, though timing varies widely from person to person. This isn’t a cure for the popping itself, but by lowering muscle force, it takes pressure off the disc and often reduces clicking as a secondary benefit.
Joint Irrigation
If your jaw locks or the popping becomes painful and doesn’t respond to conservative care, a procedure called arthrocentesis can help. A clinician uses two small needles to flush the joint space with sterile fluid under local anesthesia. This washes out inflammatory debris and can free a stuck disc. In the original study that established the technique, all 17 patients regained improved jaw mobility, and 94% experienced substantial pain reduction at four or more months of follow-up. It’s a relatively quick, minimally invasive procedure typically done in an office setting.
When Popping Is Harmless
Not all jaw popping needs treatment. A click with no pain, no locking, and no difficulty chewing is common and often stays stable for years without progressing. The joint may simply have a slight disc variation that produces noise without causing damage. Treatment becomes important when the popping is accompanied by pain, limited opening, the jaw catching or locking in an open or closed position, or headaches and ear pain on the affected side. An MRI can directly show the disc’s position and movement if there’s any question about what’s going on inside the joint.
Most people find that a combination of jaw rest, soft foods during flare-ups, targeted exercises, and a night guard is enough to significantly reduce or eliminate popping within a few weeks to a few months. The key is consistency: these strategies work best when applied together rather than one at a time.
