The masseter is the powerful muscle that closes your jaw. When it's overworked by clenching and grinding it causes jaw ache, headaches, worn teeth and a heavier, squarer jawline. Relaxing it reduces the force you can generate — easing symptoms and protecting your teeth.

Masseter Treatment for TMJ & Clenching — in detail
The masseter is the powerful muscle that closes your jaw. When it's overworked by clenching and grinding it causes jaw ache, headaches, worn teeth and a heavier, squarer jawline. Relaxing it reduces the force you can generate — easing symptoms and protecting your teeth.
1A dental problem as much as an aesthetic one
Because we're a dental practice, we look at the whole picture: worn or cracked teeth, an unstable bite, and jaw joint symptoms — not just the muscle.
For many patients the best result comes from combining masseter treatment with a well-made night guard, so the muscle calms down while the teeth are physically protected.
2Treatment and results
Two to three injections per side take a few minutes. Symptom relief typically begins within one to two weeks.
Effects last around four to six months, and repeated treatment often means longer gaps between sessions as the muscle gradually reduces in bulk.
