Temporomandibular Joint Disorder (TMJD) is a group of conditions that cause pain and loss of normal function to the temporomandibular joint (TMJ) or jaw joint. The temporomandibular joint is located in front of the ear, on both sides of the head.
The joint is made up of the lower jawbone and the skull. A cartilage disk, which functions as a shock absorber and joint lubricant, separates these two bones. The TMJ and the muscles of chewing enable you to open your mouth, talk and chew.
TMJD can originate from the chewing muscles, cartilage disk or the joint bone.
Normal Closed Position
The lower jawbone is separated from the skull by a cartilage disk that acts as a cushion when the joint is in function i.e. chewing, speaking and yawning.
Normal Open Position
On the opening of the mouth, the disk will follow the lower jaw bone and they will move together when you move your jaw up and down or side to side.
In an abnormal joint, the disk can be displaced or torn. This displaced or torn disk can cause obstruction in joint movement. A torn disk can result in excessive wear of the bone of the joint, causing inflammation and pain.
