Stress make the person in problem creates.

Stress can cause you to clench your jaw and grind your teeth. Sometimes it is simply a bad habit. Often teeth grinding is done during sleep. Also, sleeping on your stomach can result in unconsciously clenching your teeth.
Over a period of time, the muscles that control the temporomandibular joints develop nodules or "trigger points" that produce the symptoms when aggravated.
Clenching and grinding of the teeth--both of which may be TMJ symptoms--produce muscle pain, which can cause headache pain. Also, a displaced disc in the TMJ may cause pain in the joint, which is often referred into the temples, forehead or neck. These headaches are frequently so severe that they are confused and treated for migraine headaches or abnormalities in the brain.
