Jaw clenching and pelvic floor tension show up together. Women have felt this link for years. Midwives noticed it in the birth room. Now early research is starting to back it. Here is what we know and how to work with it.
What women have always felt
Ina May Gaskin wrote about the jaw and pelvic connection in childbirth. She observed that a tight jaw went with a tight birth canal, and a soft jaw went with an easier birth. She called it the Sphincter Law.
I want to be clear about what that is. It is midwifery observation, not a proven mechanism. It comes from decades of catching babies, not from a lab. But it matches what women feel in their own bodies every day. Clench the jaw and the whole system braces. Soften the jaw and something lets go downstream.
This is my experiential frame. I teach from what I have felt and seen over years of practice. I name it as such. Your lived experience counts as data in my world.
The early evidence
In 2024, a randomized trial tested the link directly. Forty-seven young women with jaw pain received a single 15-minute TMJ soft-tissue session. Afterward, their resting pelvic floor muscle activity had dropped. The jaw work changed the pelvic floor.
Read the limits with me. Small sample. Young women. One session. This is early evidence, not established therapy. It is a clue, not a cure. But it is a real clue from a real trial, and it points the same direction women have pointed for decades.
The pattern underneath
When the body feels unsafe, everything grips. The jaw. The shoulders. The pelvic floor. One system bracing as one.
Most pelvic floors are not weak. They are clenching in response to the pull. The jaw is often the first place the clench shows up. It is the most visible grip in the body. Teeth together, tongue pressed to the roof of the mouth, and the floor follows suit.
You cannot bully your body into shape. The dysfunction is in the disconnect. The issue is in the tissue. Soften the tissue and the system remembers how to let go.
How to unclench both
Start with the jaw. It is easier to feel than the pelvic floor. Notice your teeth right now. Let them part. Let your tongue drop from the roof of your mouth. Feel the small space that opens. That is the beginning.
Then slow your exhale. Your pelvic floor rides every breath. Down on the inhale, up on the exhale. A long slow exhale tells the whole system the threat has passed.
Then practice downtraining. That means learning to let go. Let your pelvic floor unclench. I say unclench on purpose and never say drop. Drop makes women picture prolapse, and that fear keeps the grip locked in place.
This is a practice, not a treatment claim. Do it at your desk. Do it in the car. Do it before bed. Small moments of unclenching add up.
Stop and get checked in person for jaw pain with clicking, locking, or pain that spreads. This work is for the chronically tight, not the newly hurt.
Keep going
This work is from my Pelvic Floor Course. The lengthening and downtraining segment teaches your floor how to let go on purpose. Release, then strength, then the letting go that makes it all hold. Let me know if you need the link!
