Waking up with a headache? Often there is grinding at night.

Why the pain is worst in the morning

During sleep, many people clench and grind unconsciously, often for hours and with considerable force. This constant strain overloads the jaw muscles, presses on the jaw joint and irritates the trigeminal nerve – the main nerve for head and facial pain. You feel the result on waking: dull pressure at the temples and forehead, a heavy head or a full-blown headache that slowly fades during the morning.

Grinding and headache: a vicious circle

Stress and an unfavourable bite position fuel the grinding. The overloaded muscles tense up, the pain disturbs sleep, and poor sleep in turn increases the tension. This creates a cycle that acute medication alone cannot break. From the perspective of CMD Systems Medicine, this is not a purely mechanical problem but a reflex, nerve-driven misregulation: the nervous system maintains a tension that nobody can switch off at will during sleep.

Typical accompanying signs

• Worn-down teeth, cracks in the enamel, sensitive teeth
• Tense, tender cheek and temple muscles in the morning
• Jaw clicking, restricted mouth opening
• Your partner reports grinding noises at night
• Neck and shoulder tension

What helps

• A splint planned on the basis of functional diagnostics. It protects the teeth and joint at night and relieves the bite position in a targeted way. A ready-made splint from the chemist protects the tooth structure but is not matched to your bite position.
• Reducing stress. Relaxation training, breathing exercises, a clear evening routine.
• Sleep hygiene. Fixed times, a screen break before sleep, avoiding caffeine and alcohol in the evening.
• Physiotherapy. It releases the tense chewing and neck muscles. You will find simple instructions under CMD exercises at home.

Important to put into perspective: measures that only dampen muscle tension do not change the underlying bite situation. Whether and how your complaints change once the function of the jaw system has been assessed and relieved differs from person to person.

When an assessment makes sense

If you regularly wake up with a headache, have signs of grinding on your teeth or your jaw clicks, a look at the jaw system is worthwhile. The CMD System Check records, among other things, muscle activity by EMG and chewing forces tooth by tooth. You can read more about this pattern of complaints under Jaw & grinding; the CMD self-test gives a first assessment.

Many of those affected also tell us about ear noises or an unsteady feeling when getting up. We see such connections between ear, balance and jaw system regularly in the clinic – a causal connection, however, has not been scientifically proven. We therefore describe it as an observation from our clinical experience and not as established knowledge. Such complaints need to be assessed by an ENT specialist first.
