Neck pain and headaches. Why they occur together.
First the neck twinges, then the head aches – often the two belong together. Here you can read how neck tension can trigger headaches, what role the jaw system plays, and what you can do immediately and in the longer term.
Many people know it: a tense, hard neck – and shortly afterwards a dull pain that pulls from the back of the head over the temples to the forehead. That is no coincidence. Neck and head are closely connected anatomically. And sometimes part of the strain sits one floor further down: in the jaw system.
Why neck tension can cause headaches
The deep neck muscles and the chewing muscles are linked with each other via shared nerve pathways in the area of the trigeminal nerve. If the neck is tense over a long period – for example through screen work with the head tilted forward – this tension can carry on upwards. Professionally, this is called tension-type headache and cervicogenic headache, that is, headache that originates from the neck. Typical is a pressing pain on both sides, “like a band that is too tight around the head”.
The often overlooked role of the jaw system
The jaw system pulls on the same network of muscles and nerves. An unfavourable bite position or teeth grinding at night (bruxism) can permanently overload the chewing muscles, and this tension can travel via muscle chains into the neck and back of the head. This can create a self-sustaining cycle of jaw, neck and head pain. Behind it lies what is called craniomandibular dysfunction (CMD): a reflex, nerve-driven misregulation in the jaw system.
In our clinical experience, looking at the jaw system is particularly worthwhile when neck pain and headaches are worst in the morning or occur together with jaw clicking and teeth grinding. That is a rule of experience, not a diagnosis – a connection can only be proven by an examination.
How certain is this, actually? For the head, face and neck, the connection with the jaw system is professionally well understood and researched. Further down in the body – spine, pelvis and feet – the evidence, on the other hand, is inconsistent: a causal connection between bite and body posture has not been scientifically proven. When we talk about it, we are talking about observations from practice and we say so. No promises can be derived from it.
Short self-check
Several “yes” answers suggest that neck and jaw system could be involved together:
- Are the neck and shoulders particularly hard and painful in the morning?
- Does the headache pull from the back of the head to the front?
- Does your jaw click, or do you grind and clench your teeth?
- Are your temples and cheek muscles tender to pressure?
- Do the complaints get worse with stress?
What helps now – in the short and longer term
Immediately: warmth on the neck, slow stretching exercises, regular screen breaks, an ergonomic workplace and consciously loosening the jaw muscles. You will find a selection in our CMD exercises at home. Physiotherapy and manual therapy are valuable companions here – they work on the muscles that are actually tense.
In the longer term: if the jaw system is also involved, this can be measured instead of assumed. The CMD System Check records, among other things, bite position, muscle activity by EMG and chewing forces tooth by tooth. If an overload shows up there, an individually made splint can relieve the jaw muscles; in our clinical experience, the neck muscles then often settle down as well. How quickly and how clearly something changes differs from person to person. The quickest first step is the CMD self-test. You can find more on this pattern of complaints under Neck & back.
When you should go to a doctor first instead of to us: with numbness, paralysis, visual or speech disturbances, with fever and a stiff neck, or after an accident or fall, you need an immediate medical or neurological assessment – not CMD diagnostics. Here the order matters more than speed.
Frequently asked questions
Why do neck pain and headaches occur together?
The neck and jaw muscles are closely linked via shared nerve pathways. If the neck is tense, the pain can pull forward over the back of the head. Overloaded jaw muscles can also transfer tension into the neck – which is why the two are often connected.
Can the jaw system trigger neck pain and headaches?
It can be involved. An unfavourable bite position and teeth grinding can overload the jaw muscles, and this tension can travel into the neck and back of the head (CMD). For the head and neck, this connection is professionally well understood. Whether it is present in your case can only be shown by an examination.
What helps quickly with neck pain and headaches?
Warmth, slow stretching exercises, posture breaks at the screen, loosening the jaw muscles and reducing stress. This relieves – it does not find the cause. With recurring complaints, an assessment is worthwhile.
When should I have neck pain and headaches assessed?
If the complaints persist over several weeks, are worst in the morning or go together with jaw clicking and teeth grinding. With numbness, paralysis, visual disturbances or after an accident, you need an immediate medical assessment.
