9 signs that your headaches come from the jaw system
- Worst in the morning. You often wake up with a headache already.
- Jaw clicking or grating when opening, chewing or yawning.
- Teeth grinding or clenching during the day or at night – often noticed by your partner.
- Tense chewing muscles. Temples and cheeks are tender to pressure.
- One-sidedness. Pain and tension tend to occur on one side.
- Neck and shoulders. Chronic tension accompanies the attacks.
- Pressure behind the eyes and sensitivity to light.
- Dental treatment as a trigger. The complaints increased after a filling, a crown or braces.
- Unremarkable findings. Neurology and imaging find no explanation.
Rule of thumb: the more of these points apply – especially morning pain together with jaw clicking or grinding – the more worthwhile it is to look at the jaw system.
The self-check in 30 seconds
Three fingers placed on top of each other should fit vertically between your incisors. If this is only possible to a limited extent or is painful, the jaw joint may be involved. Then feel the temple and cheek muscles: clearly tender to pressure? When opening slowly, watch out for whether it clicks or whether the lower jaw deviates to the side.
Important: this does not replace a diagnosis. It gives you clues, nothing more.
Why the jaw system can trigger migraine-like headaches
The trigeminal nerve is the main nerve for head and facial pain – and it also supplies the jaw joint and the chewing muscles. An unfavourable bite position can overload these muscles, irritate the nerve and carry the tension along muscle chains into the neck and back of the head. From the perspective of CMD Systems Medicine, CMD is not a mechanical disorder alone but a reflex, nerve-driven misregulation. More on this under Migraine-like headaches.
The fact that neurology often finds nothing here is not an oversight. Each specialty carefully examines its own area; nobody there measures the bite, because it does not belong to their field. Why this is so →
How to get certainty
Instead of guessing, it can be measured: the CMD System Check records, among other things, muscle activity by EMG and chewing forces tooth by tooth. This shows whether and how strongly the jaw system is involved. The first step takes two minutes: the CMD self-test.
When you should go straight to a doctor instead of to us: with a sudden, very severe headache, with fever and a stiff neck, with visual, speech or paralysis symptoms, or with a headache after a fall, you need an immediate medical or neurological assessment – not CMD diagnostics.
Frequently asked questions
How can I tell whether my headaches come from the jaw system?
Typical signs are morning pain, jaw clicking, teeth grinding, tense jaw muscles, one-sidedness, neck tension and unremarkable neurological findings. If several points apply, an assessment of the jaw system is worthwhile.
How do I test this myself?
Three fingers placed on top of each other should fit between the incisors. Feel the temple and cheek muscles for tenderness and, when opening, watch out for clicking or the lower jaw deviating to one side. The CMD self-test gives a first assessment.
Who assesses this?
A dentist specialising in functional diagnostics. Among other things, muscle activity is measured by EMG, as is the distribution of chewing forces.
What if the signs do not apply?
Then the cause probably lies elsewhere, and the neurological work-up remains the right path. CMD diagnostics are not a substitute for it, but a complement when the usual explanations do not fit.
