Neck, Jaw & Headaches

Why Does My Jaw Click or Pop When I Open My Mouth?

Usually because the small cushion (disc) inside your jaw joint shifts slightly as you open and close. Jaw clicking is very common, and if it doesn't hurt and your jaw moves normally, it's often nothing to worry about. Pain, locking or trouble opening your mouth are reasons to get it checked.

What's happening inside the joint

Your jaw joint, called the temporomandibular joint (TMJ), sits just in front of each ear. A small disc sits between the bones and moves as you open your mouth. If the disc slips a little out of place, it can click or pop as it slides back. Muscle tension and how the two sides of the jaw move together can also play a part.

Many people have a clicking jaw for years without any problems. It becomes more of a concern when it comes with pain, headaches, or your jaw catching or getting stuck.

Simple things that may help

  • Avoid opening very wide when you can, like big yawns or large bites.
  • Cut back on gum chewing, nail biting and very chewy foods during a flare.
  • Notice if you clench or grind your teeth during the day, and let your jaw relax with your lips together and teeth apart.
  • Use gentle heat on sore jaw muscles.
  • Try not to rest your chin on your hand or cradle your phone between your ear and shoulder.
  • If you grind at night, ask your dentist whether a night guard makes sense.

Stress often shows up in the jaw, so anything that helps you relax can help your jaw too.

When to see a doctor

Get medical or dental care promptly if you have:

  • Jaw pain with chest pain, shortness of breath or sweating: call 911
  • A jaw that is locked open or stuck closed
  • Jaw pain or clicking after a fall, blow or accident
  • Swelling, fever, or numbness in the face
  • Pain that keeps getting worse, or trouble eating

How physical therapy at ARI can help

A physical therapist can check how your jaw, neck and posture work together, ease tight muscles with hands-on treatment, and teach you exercises and habits to reduce pain and improve how smoothly your jaw moves. They often work alongside your dentist or doctor.
