Temporomandibular Joint Dysfunction or TMD is a set of conditions that occur where the lower jaw meets the skull. Apart from the pain and discomfort it causes, especially during the act of chewing, TMD is also known to adversely impact posture and body movement.
The Temporomandibular Joint (TMJ) hinges the jaw to the skull. When people chew, yawn or open their mouth, the joint is called into use. When the joint malfunctions, it leads to a set of conditions called Temporomandibular Joint Dysfunction, TMD for short.
