Is it a disease to dislocate the jaw when yawning?

Dislocated jaw when yawning is a disease.

Yawning dislocated jaw may be caused by local joint malformation or habitual jaw dislocation. The cause is usually sudden violence to the joint or jaw, or it may occur when opening the mouth wide, such as yawning. You should go to the hospital for an X-ray examination to get a clear diagnosis and treatment.

Symptoms of a dislocated jaw include a half-open mouth, inability to close or open, drooling, difficulty chewing, etc. A dislocated jaw can be repositioned manually, but the movement of the jaw should be restricted after repositioning.

It is recommended to eat less hard food in daily life, and use bandages to fix it at night to prevent dislocation.

Why does your jaw drop when you yawn?

In fact, yawning, laughing, coughing, banging, and chewing hard objects may all cause jaw dislocation, which is commonly known as "mandibular joint dislocation" in clinical practice.

Habitual mandibular dislocation is a manifestation of temporomandibular joint disorder syndrome. The English abbreviation of temporomandibular joint disorder syndrome is TMJD or TMD (I guess people who have lost their jaws have cursed it in their hearts). It is one of the most common diseases in the oral and maxillofacial region. It is more common in young and middle-aged people, and is most common in the 20-30 year old youth group. The main symptoms are soreness and pain in the joint area, snapping during exercise, and difficulty in opening the mouth. Some patients also have symptoms such as temporal pain, dizziness, and tinnitus. Based on this disease, yawning can easily lead to jaw dislocation.

What to do if your jaw dislocates when yawning

The jaw dislocation caused by yawning is due to the dislocation of the temporomandibular joint caused by opening the mouth too wide. The mandibular rim is surrounded by muscles, but the front wall is loose and weak. When the mouth is opened too much, the condyle and articular disc of the mandible can slide forward excessively, and anterior dislocation of the temporomandibular joint can occur.

If dislocation occurs, it is recommended to seek medical treatment immediately for reduction treatment. If it is a habitual dislocation, it can be reduced and then appropriately combined with auxiliary treatments such as acupuncture, acupressure, and physical therapy. The mouth opening should be limited within one month after reduction. Generally, the mouth opening should be limited to 1 cm. Pay special attention when yawning or biting with your mouth open. Hot compress outside the joint can help relieve pain and discomfort. Also, be careful not to eat too hard food to avoid aggravating the disease.
