The Stomatognathic System
The Most Important Body System You’ve Never Heard Of
Most people can name the digestive system, the respiratory system, and the nervous system.
Very few have ever heard of the stomatognathic system.
I certainly hadn’t.
The strange thing is that you use it every waking moment.
The word sounds complicated, but it simply refers to the structures of the mouth, jaws, teeth, tongue, facial muscles, and the joints that connect them. It is the system responsible for chewing, swallowing, speaking, breathing, and facial expression. It also plays a role in how the head and neck are supported.
In other words, it sits at one of the busiest intersections in the entire body.
Think about how many things pass through this area every day. Air passes through it. Food passes through it. Water passes through it. Words pass through it. Sensory information constantly flows from the teeth, tongue, gums, lips, jaw joints, and facial muscles into the brain.
Yet most of us give it little thought unless something hurts.
We think of the mouth as a place where food enters the body. But what if it is also a control center?
The tongue alone contains an astonishing amount of sensory information. The teeth are not simply hard tools for chewing. Each tooth is suspended by a living ligament filled with sensory receptors. The jaw muscles work throughout the day and, for many people, throughout the night. The jaw joints must coordinate with the neck, head, eyes, and balance system.
This means the stomatognathic system is not isolated. It is connected.
When you tighten your jaw, your neck often tightens. When your tongue changes position, your breathing may change. When you clench your teeth, your shoulders may rise. When your face relaxes, your entire body may feel calmer.
Many people spend years trying to improve their posture by pulling their shoulders back. Others focus on stretching tight muscles. Some chase better breathing through various techniques.
But what if part of the answer is sitting right under your nose?
Over the past year, I have become increasingly fascinated by this area of the body. Not because I think it is a magic cure for every problem, but because it appears to connect so many things that we usually think of as separate. Breathing, posture, movement, balance, eating, speaking, and relaxation all pass through this small but incredibly busy region.
The more I pay attention to it, the more I notice its influence.
When my jaw is relaxed, my breathing seems calmer. When my face softens, my neck often softens as well. When tension builds in the mouth and jaw, I can often feel it spreading into other parts of the body.
Perhaps that is why the stomatognathic system deserves more attention than it receives.
The next time you feel tension, don’t just check your shoulders.
Notice your tongue.
Notice your jaw.
Notice your teeth.
Notice the muscles of your face.
You may discover that one of the most important systems in your body has been quietly influencing everything else all along.
That realization has influenced much of my thinking in recent years. The more I study the body, the more I find that strength is not simply about stronger muscles. It is about awareness, relaxation, coordination, breathing, and learning how seemingly unrelated parts of the body work together.
Those ideas are woven throughout my book, Strong to 100. While the book is not about dentistry or anatomy, it is built on the same belief that small daily practices, applied consistently, can have surprisingly large effects on how we move, feel, and live.
The stomatognathic system is simply one more reminder that the body is far more connected than most of us realize.
