TMJ Disorders
The temporomandibular joints (TMJs) connect your lower jaw to your skull. There are two matching joints -- one on each side of your head, located just in front of your ears. The abbreviation "TMJ" literally refers to the joint but is often used to refer to any disorders or symptoms of this region. Such problems include popping sounds in the jaw, inability to fully open the mouth, jaw pain, headaches, earaches, toothaches, and various other types of facial pain.
