Headaches are one of the most common symptoms of a TMJ (temporomandibular joint) problem. A TMJ headache is a tension type of headache. It is often described as a feeling with pain in a ring around the head, or as a migraine headache.

There are a few TMJ-related causes for tension headaches. Constant contraction of muscle fibers within a muscle, create tension, pressure or a tight feeling in the face and head. Constant tight muscle fibers prevent or reduce blood flow.
The body sends more blood to the areas and this can result an increase in general blood pressure to the muscles and head, sometimes referred to as vascular headaches. Clenching and grinding the teeth, which are TMJ symptoms, produce pain from the muscles in the head, which is a headache.
These headaches are frequently misdiagnosed and treated as migraine headaches.
The pain from muscle headaches can be blocked with medications, or nerves cut with brain surgery or muscles somewhat relaxed with muscle and psychological therapy, but the cause of the disease and damage from the bad bite, malocclusion, will persist. Side effects with medications, complications from brain surgery, and limited results with muscle or psychological therapy do not correct the source of the problem.
