Know About TMJ Treatment : Your jawbone and skull are joined by the temporomandibular joint (TMJ), which sounds like a sliding hinge. There's a joint on either side of the jaw. According to Sunny Isles Dental, temporomandibular disorders, sometimes known as TMDs, include TMJ problems, which can hurt your jaw joint and the muscles that move it.It might be challenging to specify an individual's exact etiology of TMJ disorder. A combination of variables, such as heredity, arthritis, or a jaw injury, could cause pain. Although many people routinely clench or grind their teeth without developing TMJ issues, some people with jaw pain also tend to do so.
