Temporomandibular Joint Disorders also known as TMJ or TMD. The temporomandibular joint acts like a sliding hinge, connecting your jawbone to your skull. Dysfunction can lead to pain and discomfort. Jaw pain, difficulty in chewing & clicking and locking of the jaw joint are some of the symptoms. It will affect a person’s ability to speak, eat, chew, swallow, making facial expressions, and even to breathe. Clenching or grinding your teeth, tightening your jaw muscles and stressing your TM joint can lead to TMJ disorders. It can also be a result of having a damaged jaw joint due to an injury or disease. More than 90% of TMD is muscle problems which can cause headaches and other types of pain in the jaw area. The reason for this muscle problem comes from the biting action or problems with the movement of the lower jaw.
