What is TMJ?
The jaw joint ,TMJ, is a critical part of the chewing system. It is where the two sides of the mandible attach to the skull in front of each ear. A cartilage cushion floats between the bones in the joints as the mandible moves in chewing, speaking, and making facial expressions. When the cartilage becomes partially or completely displaced, various signs and symptoms are seen. An example of this is clicking in the jaw when you chew. Another part of the chewing system are the muscles in the head and neck. They cause headaches and facial pain when they over-react to an uneven bite.
