Bruxism and TMJ: How Teeth Grinding Affects Your Jaw Joint

What is Bruxism?

Bruxism means grinding or clenching your teeth. Many people do this while they sleep. However, some also grind their teeth during the day. Often, people do not know they have bruxism until symptoms appear. For example, you might notice sore jaw muscles or worn-down teeth. Bruxism can lead to many dental problems if left untreated. It is important to understand how bruxism and TMJ are connected.

Understanding the TMJ (Temporomandibular Joint)

The TMJ is the joint that connects your jaw to your skull. You have one on each side of your face, just in front of your ears. This joint lets you open and close your mouth. It also helps you chew, talk, and yawn. Because the TMJ is used so often, it can become sore or damaged. Problems with this joint are called TMJ disorders.

In severe cases, teeth grinding can damage the cartilage or muscles around the TMJ. As a result, you may develop a TMJ disorder.
