There isn’t one single best exercise for TMJ pain, but a combination of gentle jaw movements, stretches, and postural corrections consistently performs well in research. Exercise therapy reduces pain intensity in the chewing muscles by a meaningful margin compared to doing nothing, and it also improves how far you can open your mouth. Nearly 30% of the global population deals with some form of temporomandibular disorder, with muscle soreness and clicking sounds being the most common complaints. The good news is that a short daily routine of targeted exercises can make a real difference.
How Jaw Exercises Help TMJ Pain
TMJ disorders typically involve tight, overworked muscles around the jaw, stiffness in the joint itself, or both. Exercises work by gently stretching those muscles, improving blood flow to the area, and gradually restoring normal range of motion. A systematic review published in Frontiers in Oral Health found that exercise therapy significantly reduced pain intensity in the chewing muscles and improved how far participants could open their mouths, compared to people who received no treatment or education alone.
The key is consistency over intensity. You’re not trying to force your jaw open or push through sharp pain. These movements should feel like a mild stretch, never a strain.
Goldfish Exercises: Partial and Full Opening
Goldfish exercises are the most commonly recommended starting point for TMJ relief. They mimic the gentle open-close motion of a goldfish’s mouth and target both flexibility and muscle relaxation around the jaw joint.
For the partial opening version, place one finger on your TMJ (the spot just in front of your ear where you can feel the joint move) and another finger on your chin. Drop your lower jaw halfway open, then close. Your tongue should stay on the roof of your mouth throughout. This version is ideal when your jaw feels especially tight or painful, because you’re working within a comfortable range.
The full opening version uses the same finger placement, but you open your mouth as wide as you comfortably can while keeping your tongue pressed to the roof of your mouth. This stretches and strengthens the muscles that support the jaw more aggressively. Start with the partial version for the first week or two, then progress to full opening as your comfort allows. Aim for six repetitions of each, done during your daily exercise sessions.
Resisted Opening and Closing
Once basic movement feels comfortable, adding light resistance builds strength in the muscles that stabilize the jaw. These exercises are simple but surprisingly effective at retraining how your jaw moves.
For resisted opening, place your thumb under your chin and press gently upward while you slowly open your mouth against that pressure. Hold for a few seconds at the open position, then slowly close. For resisted closing, keep your thumb under your chin and place your index finger on the ridge between your lower lip and chin. Push gently downward as you close your mouth against that resistance.
The goal isn’t to create a lot of force. Think of it as about 20% effort from your thumb, just enough that your jaw muscles have to work slightly harder than they would during a normal open-close movement. This controlled loading helps the muscles around the joint coordinate better, which can reduce the clicking and popping many people experience.
Side-to-Side Jaw Stretches
Lateral stretches improve the range of motion that most people neglect. Your jaw doesn’t just open and close; it also slides side to side, and tightness in that direction contributes to overall stiffness and discomfort.
Move your jaw to the right side as far as it will comfortably go, hold for five seconds, then relax. Repeat to the left side, holding for five seconds. Alternate back and forth for ten repetitions. As you reach the end of your ten reps, try to speed the movement up slightly while still moving your jaw fully in each direction. Cambridge University Hospitals recommends this specific protocol as part of a jaw mobility routine.
If you feel a click or catch during side-to-side movement, reduce how far you’re pushing. The stretch should feel smooth throughout.
Chin Tucks for Posture Correction
This one surprises most people: your neck posture directly affects your TMJ. When your head juts forward (common if you spend hours at a desk or phone), the muscles in your neck and jaw compensate in ways that increase tension in the chewing muscles. A randomized controlled trial found that cervical stabilization training, centered on chin tucks and deep neck muscle activation, significantly improved TMJ symptom severity and corrected head posture in people with temporomandibular disorders.
To do a chin tuck, sit or stand with your back straight. Gently draw your chin straight back, as if you’re making a double chin. You should feel a mild stretch at the base of your skull. Hold for five seconds, then release. Start with 8 repetitions and gradually work up to 12 over several weeks. The movement is small and subtle. You’re not tilting your head down; you’re sliding it straight backward.
The mechanism behind this is interesting. The deep muscles at the front of your neck share a nerve pathway with the muscles that control your jaw. When those neck muscles are weak or inactive, your chewing muscles tend to overcompensate, creating a cycle of tension. Chin tucks break that cycle by restoring proper activation patterns in the neck, which in turn reduces the load on your jaw.
The “N” Resting Position
This isn’t technically an exercise, but it may be the single most impactful habit change for TMJ pain. Many people unconsciously clench their teeth throughout the day, especially during stress or concentration. That constant low-grade clenching exhausts the jaw muscles and keeps the joint under pressure.
The fix is the “N” position: place the tip of your tongue against the roof of your mouth, just behind your front teeth, as if you’re about to say the letter “N.” Your teeth should be slightly apart, and your lips barely touching. This position physically prevents your upper and lower teeth from clenching together, promoting muscle relaxation throughout the day. The technique comes from the USC Orofacial Pain and Oral Medicine Center, and they recommend maintaining it as your default mouth posture whenever you’re not eating or talking.
Try setting a few reminders on your phone for the first week. Most people are shocked at how often they catch themselves clenching once they start paying attention.
How Often to Do These Exercises
Start with two five-minute sessions per day, ideally at times when you’re already relaxed. Right after waking up and just before bed work well. During the first week, stick to this schedule and don’t overdo it. Your jaw muscles are small and can become sore from too much exercise, which defeats the purpose.
After the first week, increase frequency as tolerated. Many people find that doing a quick round of exercises three to four times daily produces the best results. Each session doesn’t need to be long. Running through partial goldfish exercises, one set of resisted opening and closing, and a few chin tucks takes about three minutes.
What to Avoid During Exercises
Never force your jaw past its comfortable range of motion. If an exercise causes sharp or shooting pain, stop immediately. A mild stretching sensation is normal; actual pain is not. Avoid wide yawning, chewing gum, or biting into hard foods during the first few weeks of your exercise program, as these put high loads on the joint that can undermine your progress.
If your jaw locks in an open or closed position, or if you experience sudden swelling around the joint, these are signs of a more serious issue that exercises alone won’t resolve. Similarly, TMJ pain that comes with ear pain, dizziness, or significant headaches may have causes beyond simple muscle tightness. In these cases, a dentist or oral medicine specialist can identify whether something structural is going on before you build an exercise routine around the wrong problem.
