TMJ (Temporomandibular Joint) Pain
The temporomandibular joint is the joint that connects your jaws to the temporal bones of the skull, i.e. the skull bones which are in front of each ear. This joint allows you to chew, yawn, talk, and move the jaw from side to side or up and down. Problems with the temporomandibular joint (TMJ) are known as temporomandibular joint disorder, though some may incorrectly call the disorder as just TMJ.
TMJ disorder can lead to pain in your jaws. There is no definite cause of TMJ pain, and it can occur due to various factors, such as a jaw injury, arthritis, poor posture, stress, teeth grinding, gum chewing or misalignment of the teeth or jaws. TMJ disorder can also cause nerve inflammation and Eustachian tube disorders.
