Coming Back to Your Breath
Many people with TMJ symptoms have observed the relationship between breathing and jaw tension.
The jaw tenses when breathing feels shallow, held, or effortful — especially during stress, concentration, or pain.
This isn’t a breathing “fault.” It’s often a sign that the body is working hard to cope.
Research into jaw pain and connective tissue sensitivity has shown that how we breathe can influence muscle tension in the neck, jaw, and upper chest, as well as how settled the nervous system feels.
How breathing and jaw tension are linked
When breathing becomes effortful or shallow, the muscles that compensate often have a direct influence on the jaw and neck.
In my practice, I have observed that a large number of people with jaw pain have very tight, overactive scalene muscles.
The scalene muscles attach to the cervical spine and the first and second ribs, where their job is to lift the ribs and create space for the lungs to fill.
They’re designed to assist breathing when demand is high — but when they end up doing most of the breathing work all the time, they become sore, restrictive, and easily irritated.
Because they attach directly to the cervical spine, this overwork creates tension in the neck that radiates naturally into the jaw.
A note on nose breathing and jaw comfort
Breathing through the mouth places different demands on the jaw, tongue, and neck than breathing through the nose. James Nestor, in Breath: The New Science of a Lost Art (p.27), documents how habitual mouth breathing causes the soft tissues of the mouth and throat to lose tone and flex inward — destabilising the airway and placing greater demand on the jaw and neck to compensate.
When the mouth is habitually open, the tongue loses its natural resting position — removing one of the jaw’s key sources of support and stability.
Breathing through the nose — when it is available — is an important foundation for jaw comfort. It supports a more settled jaw position, a stable resting place for the tongue, and reduces the need for the neck to drive breathing.
Nasal breathing also stimulates the vagus nerve, helping to calm the nervous system — which is why vagus nerve massage can be such a useful companion to breath work for jaw tension.
Nose breathing isn’t always accessible. Congestion, fatigue, or flare-ups can all make it difficult at times. This isn’t about perfection — it’s about support and gradual change.
A simple way to support nose breathing
One simple place to start is noticing where your lips and tongue rest. When the lips can rest together comfortably and the tongue rests lightly on the roof of the mouth, the jaw is usually under less strain and nose breathing is more likely to happen on its own.
This isn’t something to force. If it feels supportive, you might return to it during the day or as part of winding down for sleep.
A simple breath awareness practice
This isn’t about breathing differently or breathing “better.” It’s simply about bringing kind attention to the breath as it already is.
Find a comfortable position — sitting or lying down. Allow the breath to continue as it normally would, without trying to change it.
Notice where you can feel your breath moving in the body. It might be the rise and fall of the chest, a subtle movement in the ribs, or simply the sensation of air passing in and out. There’s no right answer — just notice wherever you naturally feel it.
On each out breath, count silently to yourself. Start at 10, and work down toward one.
If you notice your attention has drifted — a thought has come in, you’ve lost count — that’s completely normal. Simply notice it, return kindly to the count, and begin again from 10.
That’s the whole practice. You’re not trying to relax or force anything to happen. You’re simply keeping your attention in one place, with the breath as your anchor.
Even a few minutes of this during the day can help reduce the background effort the body is carrying — and give the jaw a little more room to let go.

A Reassuring Note
Simply bringing kind awareness to the breath can help relax the body.
When the body feels safe and less pressured, breathing often becomes quieter and more efficient on its own.
Daily moments of awareness can often be enough to keep the body in a state that is both relaxed and functional.

When to Seek Medical Advice
Most jaw tension and TMD symptoms are related to muscle guarding, stress, or nervous-system patterns, and they often improve well with gentle self-care.
It’s a good idea to seek medical advice if you experience:
sudden, severe, or unexplained facial or jaw pain
injury, swelling, or suspected dislocation
numbness, weakness, or changes in vision or speech
a fever, illness, or signs of infection
new pain accompanied by weight loss or general unwellness
persistent symptoms that worry you or don’t improve over time
These situations aren’t common, but it’s always appropriate to check in with a qualified medical professional if something feels unusual or concerning for you.
