What Is Bruxism?
Bruxism is repeated clenching, grinding, or tightening of the teeth and jaw muscles. It can happen while you are awake or asleep. Some people notice jaw soreness, tooth wear, facial pain, or morning headaches. Others have no clear symptoms. Bruxism often relates to stress, bite patterns, sleep problems, or muscle tension.

Key Takeaways About Bruxism
- Bruxism may happen during sleep or while you are awake.
- Jaw tension can occur even without obvious tooth grinding.
- Bruxism isn't the same as a jaw joint disorder.
How Bruxism Works
Bruxism happens when the jaw muscles contract and move the teeth together without a useful chewing task. Clenching holds the teeth in contact, while grinding moves them against each other. Sleep-related activity may occur without conscious awareness.

A clinician looks for signs such as tender jaw muscles, limited jaw movement, tooth wear, or pain near the temples. The exam may also include questions about sleep, stress, headaches, and daily habits. TMJ disorders affect the jaw joints and surrounding tissues, so they can occur with bruxism but describe a different problem.
How Bruxism Relates to TMJ Treatment
TMJ treatment may address muscle tension, jaw movement, and habits that add strain. Care can also consider neck posture because nearby muscles may affect how the jaw feels and moves.
From the Arrowhead Clinic - Lithia Springs team
When we assess bruxism, we ask about clenching, grinding, jaw soreness, headaches, and sleep habits. We also check jaw movement and muscle tenderness. Our team uses those findings to understand how jaw tension may relate to the TMJ concern being evaluated.
Bruxism in Practice: A Real-World Example
A person may wake with tight jaw muscles and temple soreness after clenching during sleep. During TMJ treatment, the care plan may address jaw movement and muscle tension linked to that pattern.
