If you get frequent headaches or migraines and nothing quite explains why, it’s worth asking a question most people never think to raise with their doctor: what’s your jaw doing?

The connection is stronger than most people expect

Research looking at the overlap between migraine and temporomandibular joint (TMJ) disorders has found the relationship runs both ways and is substantial — people with migraine are considerably more likely to also have a TMJ disorder, and people with TMJ disorders are more than twice as likely to experience migraine. This isn’t a loose correlation; there’s a clear anatomical reason for it.

The shared nerve behind both problems

The jaw, face, temples, and the coverings of the brain and its arteries are all served by the same nerve — the trigeminal nerve (the fifth cranial nerve). When the muscles that move your jaw (particularly the masseter and temporalis) become chronically tight or develop trigger points, that tension can refer pain along trigeminal nerve pathways into the temples, forehead, and behind the eyes — territory that feels identical to a tension headache or migraine, because in many cases, functionally, it is one.

This isn’t just theory — researchers have been able to reproduce tension headache symptoms in study participants simply by manipulating the temporalis muscle, in a majority of cases. That’s a striking demonstration of how directly jaw muscle tension can generate what feels like a “regular” headache.

How to tell if your jaw is the culprit

A few patterns are worth paying attention to:

• Headaches that seem to start at the temples or behind the ears rather than the back of the head
• Jaw clicking, popping, or a feeling of tightness when you wake up
• Waking with headaches specifically (often linked to nighttime clenching or grinding)
• Headaches that worsen with chewing, yawning widely, or long conversations
• A sense that massaging your own jaw or temples gives temporary relief

None of these confirm a TMJ-driven headache on their own, but together they’re a reasonable signal that it’s worth having your jaw properly assessed rather than only treating the headache in isolation. See our TMJ and jaw pain page for more on how we assess this.

Why treating “just the headache” often doesn’t work

If the actual driver is tight jaw musculature and you only ever treat the head, you’re managing a symptom while the underlying trigger keeps firing. This is a big part of why some people cycle through pain relief without ever getting ahead of the problem — the headache is downstream of something that was never addressed.

How we approach it

Trigger point and dry needling directly into the affected jaw muscles is often the most direct way to interrupt this referral pattern — releasing contracted points in the masseter, temporalis and pterygoid muscles that a standard head or neck massage typically can’t reach. For chronic or stubborn cases, we sometimes add motor point needling with electrostimulation to help reset muscles that have been over-tightened for a long time. Because neck tension so often travels with jaw tension, we’ll usually assess both together rather than treating the jaw in isolation — see our neck and shoulder pain page if that overlap sounds familiar.

Worth ruling out

Not every headache is TMJ-driven, and we won’t pretend otherwise — but if you’ve tried the standard headache playbook without much luck, and any of the jaw-related signs above sound familiar, it’s a genuinely worthwhile thing to have assessed properly rather than continuing to treat the symptom on repeat.
