Jaw clicking is caused by a small disc inside your jaw joint slipping out of position, and in most cases, you can reduce or eliminate it with a combination of habit changes, exercises, and professional treatment if needed. The disc normally acts as a cushion between the bones of the joint, but when it shifts forward, it snaps back into place each time you open your mouth, producing that distinctive pop or click. The good news: about 95% of people with jaw clicking improve with conservative, non-surgical approaches.
Why Your Jaw Clicks
Your jaw joint (the temporomandibular joint, or TMJ) contains a small, oval-shaped disc that sits between the ball of your lower jaw and the socket of your skull. When the ligaments holding that disc stretch out or the disc itself changes shape, it slides forward. Every time you open your mouth wider than about 10 millimeters, the disc pops back over the top of the jawbone, creating the click you hear. You may notice a second, quieter click when you close your mouth as the disc slips forward again.
This is called “disc displacement with reduction,” and it’s the most common form of internal jaw joint dysfunction. It’s often painless, at least at first. The clicking becomes a problem when it’s accompanied by pain, muscle fatigue, or limited jaw movement, or when the disc eventually stays stuck and your jaw locks.
Habits That Make Clicking Worse
Several everyday habits put extra stress on the jaw joint and keep the disc from settling back into a stable position. Daytime clenching or grinding is one of the biggest contributors. Research shows that people who clench during the day have a 37% higher risk of jaw pain, a 48% higher risk of chewing-related muscle fatigue, and a 51% higher risk of headaches and shoulder stiffness compared to people who don’t.
Sleep bruxism (grinding your teeth at night) also increases the risk of muscle pain and fatigue by about 52%. Poor posture, particularly hunching, independently raises the risk of headaches and shoulder stiffness by roughly 60%, even when no other harmful habits are present.
Other habits to watch for: chewing gum for extended periods, biting your nails, chewing ice, and eating foods that force your jaw to work hard. Beef jerky, bagels, raw carrots, whole apples, caramel, and anything especially crunchy or chewy all add strain to an already irritated joint.
How Posture Affects Your Jaw
If you spend hours leaning toward a screen, your head drifts forward relative to your spine. This stretches the muscles under your chin and along your throat, which pulls your lower jaw backward and downward. At the same time, your chewing muscles are working to keep your mouth closed. The result is a constant tug-of-war between two muscle groups, creating low-grade tension that pushes the disc out of alignment and increases clicking.
Forward head posture also rotates the base of your skull backward, which changes the angle at which your jaw opens and closes. Over time, this contributes to disc displacement and pain in both the jaw and neck muscles. Correcting your sitting posture, keeping your ears aligned over your shoulders, is one of the simplest interventions you can start today.
Exercises to Reduce Jaw Clicking
Jaw exercises fall into three categories: relaxation, stretching, and strengthening. Doing them consistently matters more than doing them intensely. Aim for six repetitions of each exercise, six times per day (a protocol known as the Rocabado 6×6 routine).
Tongue-on-Roof Resting Position
Place the tip of your tongue on the roof of your mouth, just behind your front teeth, and apply gentle upward pressure. This trains your jaw to rest in a relaxed, slightly open position where your teeth aren’t touching. Practice maintaining this position whenever you’re not eating or talking. It interrupts the clenching habit and gives your joint a break.
Controlled Jaw Rotation
With your tongue pressed to the roof of your mouth, slowly open and close your jaw. The tongue contact limits how far you open, which keeps the movement in a range where the disc is less likely to pop. Then, keeping your tongue in place, gently move your jaw side to side. This builds coordination in the muscles that stabilize the disc.
Resisted Closing
Place your thumb under your chin and your index finger on the ridge between your chin and lower lip. Gently push inward while slowly closing your mouth against the resistance. This strengthens the muscles that control jaw closure without overloading the joint.
Guided Opening Stretch
Relax your jaw and let your teeth part slightly. Slowly open your mouth as wide as you comfortably can while looking upward with your eyes. Hold for a few seconds, then close. Next, with your mouth closed, shift your jaw to the left while looking left with your eyes (don’t turn your head). Hold, return to center, and repeat on the right side. This improves the range of motion and helps the disc track more smoothly.
Breathing for Muscle Release
Inhale slowly for a count of five to ten, then exhale at the same pace. Jaw tension is closely tied to stress, and even a few minutes of deliberate slow breathing can reduce the baseline tightness in your chewing muscles.
What to Eat During a Flare-Up
When your clicking is accompanied by pain or your jaw feels especially stiff, temporarily switching to softer foods takes pressure off the joint and lets inflammation settle. Stick to foods that don’t require much chewing: scrambled eggs, yogurt, mashed potatoes, pasta, fish, steamed vegetables, and smoothies. Pureed soups work well on the worst days. Cut food into small pieces so you don’t have to open wide, and avoid biting into anything that forces your jaw to stretch, like thick sandwiches or whole apples.
Splints and Mouthguards
If exercises and habit changes aren’t enough, a dentist or TMJ specialist may recommend an oral splint. There are two main types, and they work differently.
Stabilization splints are flat-plane devices, typically worn at night, that prevent your teeth from fully engaging. They reduce the force generated by clenching and grinding, give overworked muscles a chance to relax, and protect the joint from compression. These are usually the first option, especially when muscle tension or bruxism is the primary driver.
Anterior repositioning splints take a more targeted approach. They guide your lower jaw slightly forward, which repositions the disc into a healthier relationship with the jawbone. This allows the stretched ligaments and tissues behind the disc to heal and tighten. These splints are typically used when a stabilization splint hasn’t resolved the clicking and imaging confirms a disc problem.
Both types aim to restore balance in the chewing system and reduce damage from unconscious habits. Over-the-counter mouthguards from a pharmacy are not the same thing. They’re bulky, poorly fitted, and can sometimes make jaw problems worse by changing your bite in unpredictable ways.
Botox for Jaw Tension
For people whose clicking is driven by chronic muscle clenching that doesn’t respond to other treatments, injections into the masseter (the large muscle along your jawline) can help. The injection weakens the muscle enough to reduce the clamping force on the joint. A typical treatment uses 60 to 100 units depending on muscle thickness, and the effects last about six months, which is longer than the typical duration when the same treatment is used in other areas of the face. It doesn’t fix the disc itself, but by reducing the mechanical stress on the joint, it can allow clicking to resolve over time.
When Clicking Becomes Locking
The progression to watch for is when clicking stops, not because the joint has healed, but because the disc has shifted so far forward that it no longer pops back into place. This is called “disc displacement without reduction,” and it typically causes a sudden, noticeable limitation in how far you can open your mouth. In the most acute stage, opening your mouth becomes nearly impossible due to the physical block of the displaced disc combined with significant pain.
If your jaw locks, a minimally invasive procedure called arthrocentesis (essentially flushing the joint with fluid to free the disc) resolves symptoms in about 80% of patients. Around 70% of those patients feel better within the first six weeks, with another 10% improving over the following three to six months. Open surgery is reserved for the small number of cases that don’t respond, and even then, success rates reach about 80% when the surgical approach is matched to the specific type of joint damage found on imaging.
Getting a Diagnosis
Most painless clicking doesn’t require imaging. A dentist or specialist can often diagnose disc displacement by feeling your joint as you open and close, listening for the click, and measuring your range of motion. When imaging is needed, CT scans are considered the gold standard for evaluating bone changes, while MRI is the preferred tool for seeing the soft disc itself and confirming exactly where it’s sitting relative to the jawbone.
Painless clicking that doesn’t limit your movement often needs nothing more than awareness, habit changes, and exercises. Clicking with pain, progressive difficulty opening, or episodes of locking warrants a professional evaluation so you can start targeted treatment before the disc displacement becomes permanent.
