The human masticatory (chewing) system consists of teeth, masticatory muscles and temporomandibular joint (jaw joint). If problems occur in the system like cramps in the masticatory muscles, or stress and damages to the jaw joints, pain will be felt. Besides, if the position of the disc inside the joint is shifted, there will be clicking sounds from the jaw joint during opening or closing of mouth.
