Clenching & grinding

Common questions about clenching & grinding

Can myofunctional therapy help with teeth grinding (bruxism)?

Myofunctional therapy can help with the muscle and posture contributors to clenching and grinding — particularly daytime clenching, low tongue posture, and mouth breathing. It does not replace a night guard if your dentist has recommended one. Coordinated care with your dentist is essential, especially for night-guard planning and monitoring tooth wear.

What is the connection between clenching and tongue posture?

When the tongue rests low in the mouth, the jaw is not supported from above. Other muscles — including the chewing muscles — pick up the load. This is one of the patterns that can lead to daytime clenching and contribute to night-time grinding. Establishing correct tongue-up posture, where the tongue rests gently against the palate, supports the jaw from above and is part of how therapy addresses clenching.

Does a night guard address the cause of grinding?

A night guard protects the teeth from wear and reduces some of the load on the joint, but it does not address the underlying muscle and posture patterns that contribute to grinding in the first place. For that reason, dentists often recommend a night guard alongside therapy rather than as a standalone solution. Therapy targets the patterns; the guard protects the teeth while that work is happening.

What is the best treatment for jaw clenching in Louisville?

Treatment depends on the cause. For daytime clenching driven by stress and posture, myofunctional therapy combined with awareness training is often enough. For night-time grinding (sleep bruxism), the most common approach is a custom night guard from your dentist plus therapy to address the muscle and posture drivers. For clenching with a TMJ component, coordinated care with a TMJ-aware dentist or oral surgeon is appropriate. At 502 MYO in Louisville, we work on the muscle and posture side and coordinate with your dentist, oral surgeon, or TMJ specialist as needed.

Is teeth grinding the same as TMJ disorder?

Not exactly. Teeth grinding (bruxism) is a behavior — clenching or grinding the teeth. TMJ disorder is a condition affecting the jaw joint itself. The two often overlap — chronic grinding can contribute to TMJ symptoms, and a TMJ disorder can make grinding worse. At 502 MYO we address the muscle and posture drivers of clenching and grinding. For TMJ-specific diagnosis and treatment (imaging, splints, joint injections), we coordinate with your dentist or oral surgeon.

Can clenching and grinding be cured?

Bruxism is rarely "cured" in the sense of disappearing forever — it is a behavior pattern that has developed over time, often in response to stress, posture, airway, and muscle factors. With therapy, the frequency and intensity of clenching and grinding typically decrease substantially, the symptom load (jaw pain, headaches, worn teeth) reduces, and you gain awareness and control over the pattern. Many patients who complete a 4-9 month program report a 50-80% reduction in symptoms and a marked improvement in jaw comfort.
