Treating TMJ issues: the jaw-pelvis connection

The jaw-pelvis connection is real! When I ask my TMD (temporomandibular disorder) clients if they also have pelvic alignment issues, most of them say yes. If your pelvis is out of alignment, most often so is your jaw, and vice versa.

When receiving bodywork to get one area realigned, the other often follows. Sometimes I have one hand in your mouth and the other on your pelvis.

Here’s how that relationship works: The pelvis includes the root of the spine, your sacrum. Your jaw — mandible — is near the upper end of your spine, and it has a special relationship with C1 and C2, the uppermost vertebrae of your spine.

Because the opening/closing motion of the jaw is both hinging and gliding, the axis of rotation is not in the TMJs but is between these two vertebrae (Guzay’s theorem). When your jaw is misaligned, it affects these vertebrae, impacting spinal and head posture and neurological well-being.

How does that happen? The dura mater is a tough, inelastic membrane that lines the inside of your cranium and forms a loose sheath surrounding the spinal cord that is attached to C1, C2, and C3 and then descends all the way down to the sacrum.

When the jaw is not aligned, it torques the dura mater at the upper end of the spine, which translates all the way down to the sacrum. This torquing can cause scoliosis, lordosis, kyphosis, pelvic rotation, head tilt, and cranial bone misalignment, which can affect your endocrine system and spinal nerves.

Conversely, a pelvic injury can affect the jaw. If your pelvis is giving you problems, put your fingers in front of your ears and open and close your jaw. Notice if your left and right TMJs feel different or the same. You may notice one side opens first or is more restricted or otherwise moves asymmetrically. You may not have pain, however.

Maybe this is why nine times more women than men suffer from TMJ disorders. Women tend to have more issues with their pelvic floors as well as hormonal imbalances. Who knows which came first?
