Headaches & the Cervical-Jaw
Look at the upper cervical spine and the temporomandibular joint and you find the originating pattern in a remarkable share of headache cases.
Most patients describe headaches by location: forehead, temples, behind the eye. The location is informative but the source isn’t always where the pain is. Look at the upper cervical spine and the temporomandibular joint — the cervical-jaw system — and you find the originating pattern in a remarkable share of headache cases.
Here’s what the system looks like clinically. The upper cervical vertebrae (C1-C2) sit at the base of the skull, where the trigeminal-cervical nucleus integrates pain signals from both the face and the upper neck. The masseter, temporalis, and pterygoid muscles of the jaw connect mechanically and neurologically to the suboccipital muscles at the base of the skull. Tension in one is tension in the other. When the jaw clenches at night (bruxism), the upper cervical muscles guard. When the upper cervical vertebrae are misaligned, the jaw compensates. Either origin shows up as a headache.
How we read it in intake
I ask: do you wake up with headaches? Are your teeth sensitive to cold or to biting? Do you hear or feel jaw clicking? Has dental work or a night guard been mentioned? Do you grind your teeth, that you know of? Do you sleep on one side preferentially? Each answer maps a piece of the system.
Why this fits the Hidden Dysfunction Model
The headache is the symptom. The cervical or TMJ dysfunction is upstream. The originating stressor is often further upstream still — chronic jaw clenching from sympathetic stress (see last month’s autonomic piece), bite asymmetry from old dental work, posture patterns from desk work. Treating the headache without addressing the cervical-jaw system gives short-term relief and long-term recurrence.
What we do
Cervical chiropractic adjustment for the C1-C2 segments, soft-tissue work on the masseter and temporalis, occasionally referral to a dentist for night-guard or bite assessment, sometimes Active Release Technique on the suboccipitals. When the autonomic story is part of the pattern, we work on that simultaneously.
Call the office if your headaches have a pattern. There’s usually one to find.
