What Is Bruxism?
Bruxism is a pattern of clenching, grinding, or tightening the teeth and jaw muscles, often during sleep or periods of concentration. The activity may occur without conscious awareness and can place repeated stress on the teeth, jaw joints, and nearby muscles. Daytime and sleep-related forms describe when the behavior occurs.

Key Takeaways About Bruxism
- Jaw tightening may happen without conscious awareness.
- Bruxism describes a behavior, not a single cause.
- Jaw pain is not always caused by bruxism.
How Bruxism Works
Bruxism involves repeated activation of the jaw muscles that close or stabilize the mouth. Clenching holds the teeth together, while grinding adds movement across the tooth surfaces. Sleep-related activity may occur without awareness, while awake activity can appear during concentration, stress, or sustained effort. The pattern can be assessed through reported symptoms, observed tooth wear, muscle tenderness, and jaw movement.

TMJ describes the jaw joints that help the lower jaw open, close, and move side to side. Bruxism can increase the workload on these joints and the surrounding muscles, but joint symptoms can also have other causes. A clinical review considers the jaw, neck, bite, and reported habits together so the term describes a pattern rather than a single symptom.
From the Arrowhead Clinic Chiropractor Newnan team
When we check bruxism during TMJ Treatment, we ask about daytime clenching, sleep-related grinding, jaw fatigue, and tooth sensitivity. We also assess jaw movement, muscle tenderness, and the way the teeth meet. These findings help us distinguish a clenching pattern from symptoms that may involve other structures.
Bruxism in Practice: A Real-World Example
A person who works at a computer may hold the jaw tight during focused tasks and later notice facial fatigue or morning jaw stiffness. A TMJ Treatment assessment can document the pattern alongside jaw movement and muscle tenderness.
