Why Does My Jaw Lock or Feel Stuck?

If your jaw sometimes catches, won’t open all the way, or gets stuck in an open or closed position, it could be a sign of a temporomandibular disorder. It’s common for your jaw to click now and then without pain, but if you keep having TMJ locking, pain, or trouble moving your jaw, it’s time to get it checked out.

What Can Make Your Jaw Lock?

Your temporomandibular joints are right in front of your ears and help your jaw move when you talk, chew, or yawn. According to the National Institute of Dental and Craniofacial Research, symptoms of TMD can include stiffness, limited jaw movement, and locking.

A small disc cushions each joint. Changes in how the disc and joint move, inflammation, muscle tightness, clenching, or an injury can make the jaw catch, so the cause can’t be determined from the sensation alone.

What Does TMJ Locking Feel Like?

Your jaw feels stuck if it stops moving before it should or you have to shift it to open your mouth normally. Sometimes it only lasts a few seconds, comes back when you eat, or makes it hard to open wide.

Other clues may include:

• pain or tenderness near one or both jaw joints
• a painful click, pop, or grinding sensation
• trouble biting, chewing, speaking, or yawning
• headaches, facial soreness, or nighttime clenching

If your jaw makes a sound but moves normally and doesn’t hurt, you usually don’t need treatment. If your jaw stays locked, locks after an injury, or you notice swelling, fever, or severe pain, you should see a professional right away.

How Is a Locked Jaw Evaluated?

An American Family Physician evidence review explains that TMD evaluation begins with your history and a physical examination. Your dentist may check tenderness, jaw tracking, opening range, joint sounds, muscle tension, and whether movement reproduces the pain.

You won’t always need imaging. Your dentist may suggest it if the diagnosis isn’t clear, your symptoms are unusual, you’ve had an injury, or if simple treatments haven’t worked. Don’t try to force your jaw open if it’s blocked and painful while you wait for your appointment.

FAQ About a Jaw That Locks

Can stress make my jaw feel stuck?
Stress can make you clench your jaw or tighten your muscles, which can make jaw pain or limited movement worse.

Is jaw locking always caused by TMJ?
No. Things like trauma, infection, or dental problems can also affect how your jaw moves, so you may need an exam to find out what’s going on.

Should I seek care if my jaw unlocks on its own?
If your jaw keeps locking, it’s still a good idea to get it checked out, especially if it makes eating, speaking, or opening your mouth harder.
