Coming Back to Your Breath
Many people with jaw tension notice that their 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.
Clinical educators working with jaw pain and connective tissue sensitivity have 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.
In practice, many people with jaw pain rely heavily on the muscles at the front and sides of the neck to breathe. When these muscles are doing most of the work, they can become overactive, sore, and restrictive — which can contribute to neck discomfort and jaw tension.
Why breathing patterns matter for jaw tension
Breathing doesn’t just involve the lungs. It also involves muscles in the neck, chest, and upper body that help move air in and out.
When the body is under stress, or when breathing becomes shallow or effortful, these muscles often work harder than they need to — especially the muscles at the front and sides of the neck.
In my practice, a large number of people with jaw pain have very tight, overactive scalene muscles. These muscles are designed to assist breathing when demand is high, but when they are doing most of the breathing work all the time, they can become sore, restrictive, and easily irritated.
Because the scalenes sit close to the jaw, neck, and nerves of the upper chest and arms, this overwork can contribute to a pattern of tension that affects the jaw as well as the neck and shoulders.
Coming back to easier breathing
This guide isn’t about changing how you breathe or trying to breathe “correctly.” It’s about exploring ways your breath might feel easier and less effortful.
For many people with jaw tension, breathing has gradually shifted upwards into the neck and chest. This can happen quietly over time, especially during prolonged stress, pain, or periods of high demand.
When breathing becomes less effortful and more evenly shared through the body, the muscles around the neck and jaw often don’t need to work as hard.
Exploring breath in this context isn’t about control or performance. It’s about noticing comfort, ease, and what feels supportive for you in that moment.
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.
When the mouth is habitually open, the jaw is more likely to be held forward or unstable, the tongue loses its natural resting support, and muscles in the neck are required to work harder to help maintain the airway.
Over time, this increased demand can contribute to jaw strain, neck muscle overactivity, and patterns of clenching or holding — particularly during stress and sleep.
For these reasons, 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.
Nose breathing isn’t always accessible. Congestion, fatigue, illness, 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. If it doesn’t, it’s information — and something to leave aside for now.
Supporting the neck and breathing muscles
When breathing becomes effortful, muscles in the neck often step in to help move air in and out.
These muscles are designed to assist breathing during increased demand, but when they are working hard all the time they can become sore, tight, and protective.
In people with jaw tension, this often shows up as persistent tightness at the front and sides of the neck, sensitivity around the collarbones, or a sense that the neck is always “doing the work.”
Supporting these muscles isn’t about stretching or forcing release. It’s about reducing the overall load placed on them, so they don’t need to stay switched on all the time.
Approaches that support easier breathing, jaw comfort, and a sense of safety in the body often allow neck tension to soften gradually, without direct intervention.
Other ways to support your breath
Supporting your breath doesn’t require long practices or special techniques.
Often it’s the smaller, repeatable things — easing unnecessary effort in the jaw, neck, and shoulders, allowing natural pauses, or noticing when breathing feels strained — that make the biggest difference.
During flare-ups especially, doing less, more often is usually more supportive than trying to breathe “better” or do more.

A Reassuring Note
Breathing patterns can change.
When the body feels safer and less pressured, breathing often becomes quieter and more efficient on its own — without effort or control.
Supporting ease in the breath can be an important first step toward reducing jaw tension and restoring comfort.

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.
