Jaw cracking refers to a clicking or snapping sound in your jaw. Its also known as jaw popping.

Often, the sound occurs with jaw pain and discomfort. You might also have a hard time moving your jaw, depending on the underlying condition.

Jaw cracking usually isnt a cause for concern, though. It can even happen when you widely yawn or open your mouth.

The exception is if you recently sustained a facial injury, which can dislocate or break your jaw. In this case, youll need emergency help.

Read on to learn about the possible causes of jaw cracking and when you should see a doctor.

The potential causes of jaw cracking range in severity and type. They include:

Your temporomandibular joint (TMJ) attaches your jawbone to your skull. If theres something wrong with this joint, its called temporomandibular joint disorder (TMD).

TMD can make your jaw crack or pop. Other symptoms include:

TMD often happens without a specific cause. Occasionally, clenching your teeth due to emotional stress can play a role.

Arthritis occurs when your joints become damaged and inflamed. If it affects your TMJ, it can cause TMD and jaw cracking.

All types of arthritis can lead to TMD. Most cases are due to osteoarthritis, but it can also be caused by rheumatoid arthritis.

Arthritis also causes symptoms in other parts of your body, including:

Facial injuries can dislocate or break your jaw. A dislocation happens when your jawbone moves out of place, while a broken jaw happens when your jawbone breaks.

OSA increases your chances of developing TMD. The connection is unclear, but its thought that the resistance in your airways triggers a stress response. This may cause your jaw muscles to clench together.

Other symptoms include:

Malocclusion of the teeth occurs when your upper and lower jaws are misaligned. It causes your upper and lower teeth to line up incorrectly.

There are several types of malocclusions, including:

The primary symptom is teeth misalignment, but you can also experience TMD and jaw noises.

Try eating softer foods to decrease your jaw activity. If your symptoms persist, see a doctor.

If you have jaw cracking, pay attention to your other symptoms. This can help you determine what might be causing the sound. Be sure to visit a doctor if you have persistent pain, difficulty eating or breathing, or if the jaw cracking gets worse.
