What is TMJ?
TMJ is the acronym used to describe your temporomandibular joint, which connects your lower jaw to your skull. It is one of the most complex joints in your body, and is responsible for many important functions such as chewing, talking, and yawning.
TMJ is often used incorrectly to refer to temporomandibular joint disorder (TMD), the condition that occurs when your temporomandibular joint (TMJ) becomes misaligned. TMD, also referred to as TMJ disorder, is a common condition affecting many Americans and can result in serious, debilitating pain.
