What is temporomandibular disorder?
Temporomandibular (TMD) disorder, also known as temporomandibular joint (TMJ) syndrome, is a disorder of the jaw muscles and nerves. It’s usually caused by inflammation or injury to the temporomandibular joint, which connects the skull to the jawbone.
Anything from a tooth or jaw injury, teeth misalignment, teeth grinding, stress, bad posture, and even gum chewing can cause this condition. Women ages 18-44 have increased risk of developing the syndrome. People who are genetically predisposed to pain sensitivity and an increased stress response are also more susceptible.
