If your jaw is stuck open or locked to one side, the joint connecting your lower jaw to your skull has slipped out of position. A mild slip (subluxation) often resolves on its own with gentle relaxation, but a true dislocation locks the jaw open and requires someone else to manually guide it back. Knowing which situation you’re in determines what you should do next.
Subluxation vs. True Dislocation
Your jaw joint works like a hinge-and-slide mechanism. The rounded end of your lower jawbone (the condyle) sits in a shallow socket and glides forward when you open wide. Sometimes it glides too far forward, past a bony ridge called the articular eminence, and gets stuck there.
A subluxation is a partial slip that you can correct yourself. Your mouth may feel stuck momentarily, but with some wiggling or relaxation, the jaw slides back. This is common, often painless, and not an emergency. A true dislocation (luxation) means the condyle is fully locked in front of that bony ridge and the surrounding muscles have gone into spasm, holding it there. You cannot close your mouth, talking is difficult, and it hurts. This requires another person, typically a medical professional, to push the jaw back into place.
What to Do for a Mild Jaw Slip
If your jaw clicks, pops, or momentarily catches but you can still close your mouth, you’re dealing with a subluxation or disc issue rather than a full dislocation. Try these steps:
- Relax completely. Stop trying to force your mouth closed. Panicking tightens the muscles around the joint and makes things worse. Take slow breaths through your nose.
- Place your tongue on the roof of your mouth. Position the tip just behind your upper front teeth. This naturally discourages the jaw from sliding too far forward.
- Gently guide the jaw. Place one hand under your chin. Apply light downward and backward pressure while slowly trying to close. The motion should be smooth and controlled, never a sudden jerk.
- Apply warmth. A warm washcloth against the side of your face can help ease muscle tension around the joint.
If the jaw slides back with a soft click and you can close normally, the episode has resolved. But if your mouth remains locked open, you’re looking at a true dislocation.
How a Dislocated Jaw Is Reduced
A true jaw dislocation is reduced (put back) using a technique that dates back centuries. It requires trained hands, and here’s why: the procedure involves applying steady downward pressure on the back teeth to pull the condyle below the bony ridge it’s stuck in front of, then pushing the entire lower jaw backward so the condyle drops back into its socket. At the same time, the chin is rocked slightly upward to help the joint clear that ridge.
This takes firm, continuous force, not a quick shove. The muscles around the joint are in spasm, actively fighting the repositioning, so relaxation is critical. If you can’t relax enough for the procedure to work, sedation or a muscle relaxant may be used to calm the spasm. The reduction itself causes pressure but not sharp pain, and once the condyle slips back into the socket, relief is almost immediate.
Attempting this on yourself is extremely difficult because you can’t generate the right angles of force inside your own mouth while your jaw muscles are locked in spasm. Having an untrained person try it risks fracturing the jawbone, damaging the joint further, or injuring the soft tissue. When the jaw snaps back into place, it does so suddenly, and even trained practitioners position their thumbs carefully to avoid being bitten.
When It’s an Emergency
A dislocated jaw always warrants medical attention, but certain signs make it urgent. Difficulty breathing, heavy bleeding, severe facial swelling, or numbness in part of your jaw or face all signal that something beyond a simple dislocation may be happening, such as a fracture or airway compromise. If any of these are present, call emergency services rather than heading to an urgent care clinic.
Recovery After Reduction
Once your jaw is back in place, the joint and surrounding ligaments need time to heal and tighten back up. For at least three weeks after a dislocation:
- Eat soft foods that don’t require wide opening or heavy chewing.
- Support your jaw with your hands whenever you yawn or sneeze to prevent the joint from slipping forward again.
- Avoid extreme opening, including biting into large sandwiches, dental work that requires prolonged wide opening, or anything that forces the jaw to its limit.
- Skip hot foods and drinks in the first few days, as heat can increase swelling around the joint.
Your doctor may wrap the jaw with a supportive bandage (called a Barton bandage) to hold it in place during the initial healing period. This keeps the jaw immobilized so the stretched ligaments can recover. A short course of anti-inflammatory medication or a muscle relaxant may also be prescribed to manage pain and prevent the muscles from spasming again.
Exercises to Stabilize the Joint
If your jaw has slipped out more than once, or if you get frequent clicking and catching, targeted exercises can retrain the muscles and ligaments to keep the condyle where it belongs. One widely used program is the Rocabado 6×6 protocol: six exercises performed six times each, six sessions per day, for about six weeks. The exercises focus on:
- Tongue positioning: Keeping the tongue on the roof of the mouth to train a resting jaw posture that limits forward slide.
- Controlled hinge opening: Opening the mouth in a pure rotational motion (like a hinge) rather than letting the jaw slide forward, by keeping the tongue pressed to the palate during opening.
- Resistance training: Using your fingers to gently resist the jaw as it moves side to side and open and closed, building stability in the supporting muscles.
- Posture correction: Chin tucks and shoulder blade squeezes that improve head and neck alignment, which reduces strain on the jaw joint.
These exercises won’t fix an acute dislocation, but they can significantly reduce the chance of it happening again.
Why Jaw Dislocations Tend to Recur
Once the ligaments around the jaw joint have been stretched by a dislocation, they’re more likely to allow it again. Each episode stretches the capsule a little more. People with naturally loose joints (hypermobility), those who open their mouths very wide during dental procedures or yawning, and those with shallow joint sockets are at higher risk.
For people who experience repeated dislocations despite conservative treatment and exercise, surgical options exist. These include tightening the joint capsule (capsulorrhaphy), reshaping the bony ridge the condyle gets stuck on (eminectomy), or shortening the ligaments that hold the joint together. Surgery is typically reserved for chronic cases where the jaw is dislocating frequently and affecting quality of life.
The Bottom Line on Popping It Back Yourself
If your jaw is merely clicking or briefly catching, gentle self-management with relaxation, tongue positioning, and careful guidance often works. If your mouth is locked open and you cannot close it at all, that’s a true dislocation, and you need professional reduction. The technique requires specific hand positioning, controlled force in multiple directions, and the ability to manage complications. Getting to an emergency department or oral surgeon is the fastest path to relief, and most reductions take only minutes once you’re in the chair.
