Jaw Pain / TMJ Dysfunction / Bruxism

What is TMJ dysfunction?

The temporomandibular joint is the hinge on either side of your face that connects your lower jaw to your skull. It is one of the most frequently used joints in the body, involved in every bite, yawn, and word you speak. When something goes wrong with it, whether that is tension in the surrounding muscles, restriction in the joint itself, or a combination of both, the result is what is commonly called TMJ dysfunction or temporomandibular disorder.

Symptoms vary quite a bit from person to person. Some people have pain in the jaw itself. Others feel it in the face, the temples, or the ear. Headaches are very common, particularly across the forehead or at the sides of the head. A clicking or popping sound when opening and closing the mouth is often present, though clicking on its own, without pain or restriction, does not always need treatment. In more acute cases the jaw can feel locked or very difficult to open fully.

One thing worth understanding is that the jaw does not exist in isolation. It is closely connected to the neck and upper back, and tension in those areas is very often part of the picture. Someone who carries a lot of tension in their shoulders and neck, or who has been dealing with postural strain at a desk, may find that this is feeding directly into their jaw symptoms. It is one of the reasons that jaw pain does not always respond well to treatments that focus on the jaw alone.

What is teeth grinding?

Teeth grinding, or bruxism to give it its clinical name, is the habit of clenching or grinding the teeth, most often during sleep. Many people have no idea they are doing it until a dentist spots the wear on their teeth, or a partner mentions it. Others are more aware, noticing that they clench when concentrating, driving, or under stress. Bruxism and TMJ dysfunction are closely related but not the same thing. Grinding and clenching put significant load on the jaw muscles and joint over time, which is one of the most common ways TMJ problems develop. But bruxism can also cause symptoms of its own: jaw ache, facial tension, headaches, and disrupted sleep. Some people have one without the other; many have both.

What tends to cause it?

Stress is probably the most common factor behind both conditions. When we are under pressure, many of us clench or grind without realising it, often during sleep. Over time this overloads the muscles around the jaw and the joint itself. Dental treatment, particularly anything that requires the mouth to be held open for a long period, can also bring on symptoms. So can a knock or injury to the jaw or face, changes in bite following dental work, or a long period of poor posture that has affected the neck and upper back. In some people there is no clear trigger. The symptoms develop gradually, and by the time they come in for help, tracing back to a single cause is not really possible or necessary. What matters is what is happening now and what can be done about it.

How we treat jaw pain and teeth grinding at BTC

Osteopathic assessment is the right starting point for both jaw pain and teeth grinding. It is a particular area of clinical interest and experience within our team, and our osteopaths take a broad view of it, looking at the jaw itself, the muscles of the face and neck, the cervical spine, and the upper back, to build a clear picture of what is driving your symptoms.

Treatment typically involves hands-on work to release tension in the muscles around the jaw, restore movement in the joint, and address any contributing restrictions in the neck or upper back. For patients whose symptoms are largely driven by grinding and clenching, the focus tends to be on the muscular load that bruxism places on the jaw and the knock-on effects that creates. The approach is tailored to what the assessment finds, so no two treatment plans look exactly alike.
