As a dental specialist, I see many people who have headaches because of changes to their dental bite or temperomandibular joint over time. These changes are often associated with habitual clenching or grinding of teeth when asleep and sometimes during the day.
This National Institute for Health and Clinical Excellence summary overlooked dentally related causes (or potentiators) of headache and migraine, which are increasingly being treated by removable and reversible dental appliances or more permanent correction of dental occlusion problems.1 2 3 4
We now routinely ask patients about headache symptoms. It is not surprising that activation of the masticatory muscles, such as temporalis, where forces can be as high as 100 kg or more during clenching, can push people past their “threshold” and cause symptoms such as headaches to dominate.
A simple removable dental appliance could be a drug-free solution for a large proportion of people with headache. It is worth remembering this when considering a differential diagnosis and possible treatment or referral options in people who present with headache.
