Most people have heard of TMJ, a commonly used abbreviation for what is actually called Temporomandibular joint dysfunction (TMD), but not all know what it is, how it is caused, or what can be done to relive the pain associated with this common disorder. Determining if you are suffering from TMJ Disorder, or TMD, can be incredibly helpful, though, especially since your dentist might be able to offer you quick relief from jaw pain and associated symptoms. By relieving tightness throughout your hard-working jaw joints, TMD treatment can help eliminate discomfort throughout the jaw, and even protect your teeth from undue wear that could lead to noticeably jagged edges, heightened sensitivity and other damage. If you are unsure if you have TMD, the following quiz can help you learn the most common symptoms of the disorder.
