Is Laughing Too Hard Dangerous? - Face ForWard Orthodontics

Can laughing be dangerous to your health?

For one Chinese woman, laughing became pretty serious when she laughed so hard her jaw became stuck open. The woman, who was traveling on a high-speed train to Guangzhou in South China, reported that she was laughing uncontrollably for several minutes, and while she was laughing, her jaw locked open.

Fortunately for the woman, a doctor was on board the train and was able to offer assistance by resetting her jaw.

This wasn’t the first time the woman experienced dislocation of her jaw. In the past, she also had the not-so-fun experience because of frequent vomiting during pregnancy.

“Your jaw becomes easier to dislocate after the first time it happens,” said Dr. Darin Ward of Face ForWARD Orthodontics in Dallas, Texas.

When your jaw is stuck in the open or closed position, it can be a little scary.

It can also cause damage to the temporomandibular joints (TMJs), which are located in front of the ears on either side of the head and connect the lower jaw to the skull.

The TMJs allow the jaw to move up and down, back and forth, and side to side.

“The TMJs play a very big role in the ability to bite, chew and speak,” Ward said.

When the TMJs become dislocated or damaged, individuals can develop temporomandibular joint disorder, or TMD.

“Damage to the TMJs can happen from use, age or injury,” Ward said.

Some individuals experience wear and tear on the jaw joints as a result of arthritis or other health conditions, too.

But, the primary cause of TMD is an unbalanced bite.

“When the bite is unbalanced, the pressure on the jaw is unbalanced when in use and at rest,” Ward said.

Individuals with unbalanced bites also frequently grind their teeth or clench their jaw, which means additional pressure on the TMJs.

TMD is often very painful and also causes stiffness, creaking, popping and snapping of the jaw joints, and locking in an open or closed position.

Other symptoms include muscle tension in the jaw, pain in the temples, headaches, migraines, unexplained ear pain, and facial pain.
