While it’s not known what causes a TMD, it could be something as simple as consistent teeth grinding. TMJ pain has been reported in 1 in 10 people, and TMD has been reported in almost half of the population of the United States.
There are no specific statistics about TMJ headaches because it can be hard to distinguish between general headaches and TMJ headaches.
The muscles of the TMJ run along your jaw and cheeks, and sometimes these muscles can cause pain — even headaches. When the muscles in your jaw tense up — like when you grind your teeth — the pain can spread to other TMJ muscles alongside your cheeks and on the sides and top of your head, causing a headache.
A TMJ headache might also result from TMJ issues related to osteoarthritis, joint hypermobility, or osteoporosis.
There can be a direct link between head and neck pain and oral health. For many people experiencing all over neck and neck pain, visiting with your dentist may provide clues to help you find the solution to those problems.
During any thorough examination of your teeth, dentists might ask whether you’ve been experiencing any headaches or neck pain. They know better than most how your mouth and teeth can cause residual pain in your body.
