Most people think they will have neck or back pain when they are hit from behind. Jaw pain is something that people don’t always notice right away. More people than you might think have TMJ pain after a rear-end collision. The temporomandibular joint connects the jaw to the skull and helps protect the jaw from sudden movements. When you hit someone from behind, your head can snap forward and back, which puts a lot of stress on this joint even if you don’t touch it directly.

Why You Get TMJ Pain After Being Hit From Behind

The jaw may automatically clench when you hit something. This sudden tightening can put stress on the joint and the muscles around it. Sometimes, the lower jaw moves out of place a little, which causes swelling and pain that doesn’t go away. Symptoms of TMJ pain after a rear-end collision may not show up for hours or days, making it harder to see the link.

Airbags and headrests can also hurt the jaw if they hit the face. Even a light touch can hurt the soft tissues or nerves around the jaw. Swelling in the joint can make it hard to move, which can make it hard to chew or talk.

Things to Look Out For

People with TMJ pain often say they have headaches, ear pain, or a stiff jaw that makes clicking or popping sounds. Some people have trouble fully opening their mouths. Facial injuries can also make the cheeks or temples feel sore. Stress or moving your jaw in the same way over and over can make these symptoms worse.

Why People Don’t Always Notice TMJ Injuries

After a rear-end crash, people usually pay more attention to their neck and back. At first, the signs of a jaw injury may not seem like a big deal, and it’s easy to ignore them. But if you don’t get treatment for TMJ problems, they can become long-term and make it hard to do things like eat and sleep.
