What is a Dislocated Jaw?
Simply put, a dislocated jaw means your jaw joint has slipped out of its normal spot. Doctors call this joint the temporomandibular joint, or TMJ for short.
Think of your TMJ as a tiny door hinge that connects your lower jaw to your skull. This joint, along with nearby muscles and bands of tissue called ligaments, lets you talk, chew, and move your mouth.
When your jaw dislocates, these parts stop working together smoothly. Doctors consider this a medical emergency because you cannot eat, drink, or speak properly until it is fixed.
What Are the Symptoms of a Dislocated Jaw?
A dislocated jaw causes sharp, intense pain. You might also notice several physical signs right away:
- You cannot close your mouth. Your mouth may stay stuck open.
- Your jaw looks crooked. One side may look out of place or shifted.
- Your bite feels wrong. Your upper and lower teeth do not fit together correctly, which doctors call an open bite.
- Speaking is hard. Your words may sound slurred or unclear.
- You drool. Because you cannot close your mouth, saliva escapes easily.
- Your ears feel blocked. You might feel strange pressure near your ear canals.
Imagine trying to talk or close your mouth after a sudden pop, only to find you cannot move it back. Knowing these signs helps you get help right away.

Check Availability →What Causes a Dislocated Jaw?
Several everyday actions and unexpected events can cause your jaw to pop out of place.
- Opening your mouth too wide: This happens during deep yawns, big laughs, or when taking a large bite of a tall sandwich or burger.
- Direct impacts to the face: Getting hit during sports, a fall, or a physical accident can force the jaw bone out.
- Certain health conditions: Some people have loose joints due to connective tissue disorders like Ehlers-Danlos Syndrome. This makes their joints move beyond normal limits.
- Seizures: Severe muscle contractions during a seizure can pull the jaw out of alignment.
- Medical procedures: Keeping your mouth open wide for a long time during dental work can also trigger a dislocation.
How Do doctors Diagnose Jaw Dislocation?
When you visit a doctor for a dislocated jaw, they will first ask how it happened. They want to know if it occurred during a yawn, a sports injury, or dental work.
Next, they will gently check your lower jaw and test your bite alignment. Your doctor may order an X-ray to see how far the jaw bone has moved away from your skull base.
How Do doctors Treat a Dislocated Jaw?
Doctors have used a similar treatment method for thousands of years. A famous ancient Greek doctor named Hippocrates, often called the father of medicine, first described this technique around 460 BCE.
Today, doctors call this technique manual reduction.
What is Manual Reduction?
During manual reduction, your doctor uses their hands to guide your jaw back into its socket. They place their thumbs inside your mouth on your lower teeth and support your chin with their fingers.
Then, they gently push the jaw downward and backward into place. To keep you comfortable, your doctor may give you a mild sedative, numbing medicine, or general anesthesia.
A dislocated jaw is a medical emergency. Getting treatment quickly makes manual reduction much easier and faster.
What If Your Jaw Keeps Dislocating?
If your jaw pops out of your TMJ socket over and over again, your doctor may suggest surgery. This procedure strengthens the connection between your jaw bone and skull.
Surgeons can tighten the ligaments around your joint or build a small bone barrier to stop the jaw from slipping out too easily.
Can I Prevent Dislocated Jaws?
You cannot prevent every jaw dislocation, especially those caused by unexpected falls or car accidents. However, you can take simple steps to lower your risk:
- Talk to your dentist: If you need long dental procedures, tell your dentist if you need short breaks to rest your jaw muscles.
- Cut food into smaller pieces: Avoid taking giant bites of tall burgers or sandwiches. Cut your food up to protect your jaw joint.
- Protect your yawns and laughs: Support your chin with your hand when you feel a huge yawn coming on.
- Be careful with loose joints: If you have hypermobile joints, avoid activities that stretch your jaw too far.
What Can I Expect If I Have This Condition?
After a successful manual reduction, most people take about six weeks to heal fully. Your doctor may recommend specific recovery steps:
- Wear a special bandage: A Barton bandage helps keep your jaw stable while the tissues heal.
- Support your chin: Place your hand under your chin when you yawn, sneeze, or cough to keep your mouth closed.
- Use ice and medicine: Apply ice packs to reduce swelling and take over-the-counter pain relievers like NSAIDs as directed.
- Eat soft foods: Stick to liquids, soups, yogurt, and mashed foods until your doctor says you can eat solid items again.
⚠️ When to Seek Emergency Medical Help.
Once your jaw dislocates once, it is more likely to happen again. If your jaw pops out of place:
- Go to the nearest emergency room (ER) or call 911 (US/Canada) or 999 (UK) right away.
- Do not try to push the jaw back into place on your own, as this can cause muscle spasms or tooth damage.
- Seek medical care right away if you have trouble breathing, severe bleeding, or an inability to swallow.
How Do I Take Care of Myself?
Giving your body time to heal is the best thing you can do. While manual reduction offers instant relief, your jaw tissues need weeks to recover.
Follow your doctor's instructions closely, avoid hard foods, and protect your jaw from sudden movements.
