Symptoms Worth Paying Attention To
The most common signs that something is going on with the temporomandibular joint or the surrounding muscles include clicking, popping, or grinding sounds when you open or close your mouth, jaw pain that is worse in the morning or after meals, difficulty opening your mouth fully or a jaw that locks temporarily, headaches that start at the temples or the back of the head, ear pain or a feeling of fullness in the ears without any infection, neck and shoulder tension that does not resolve with massage or stretching, and teeth that feel sore or sensitive without any cavities to explain it.
Clenching and grinding, which we have covered in depth on our nightguard page, is both a cause and a consequence of TMJ disorder. The relationship between grinding and jaw pain is bidirectional: grinding creates forces that strain the joint and surrounding muscles, and joint dysfunction makes the grinding worse. Many patients with undiagnosed TMJ disorder grind heavily at night and wake with headaches or jaw soreness that they have normalized over years without realizing the two are connected.
