Your jaw and your breath: a connection that you can’t imagine

Have you noticed your jaw clenching, as if it were working on its own? That’s bruxism, and many times the origin is not in your mouth… but in how you breathe.

The diaphragm is a large, dome-shaped muscle just below the lungs. It moves up and down every time you breathe. When you are relaxed and breathing well, it works without a problem. But if you are stressed or have bad posture, your diaphragm becomes blocked and you start breathing only with your chest. This is called high chest breathing… and it can trigger bruxism.

When you breathe like this, the muscles of the neck, face and head do extra work that is not theirs to do. The result: tension in the craniofacial area, headache and clenched jaw.

How it all connects

Osteopaths explain it clearly: if the diaphragm does not move well, the whole body gets out of balance. To compensate, you activate more muscles in the upper area and that can lead to bruxism, sleep problems and more stress.

Myofunctional therapy also confirms this. This discipline trains muscles of the face, tongue and breathing. A poorly positioned tongue when swallowing or breathing can contribute to jaw tension. That is why breathing through the nose and not through the mouth is essential to protect your jaw and control stress.

Posture also has an influence: spending hours hunched over in front of a cell phone or sitting incorrectly blocks the diaphragm, strains the neck and jaw and favors bruxism.

Breathing as a tool

When you breathe using the diaphragm, your body and mind relax. In addition, you activate the vagus nerve, a real calming button that reduces stress and jaw tension.

So, if you notice your jaw clenching, don’t just wear a mouth guard. Watch your breathing, watch your posture and listen to your body’s signals. Relax your abdomen, breathe through your nose and let your diaphragm work… your jaw and your mind will thank you.
