TMJ is an acronym for the temporomandibular joint, otherwise known as the lower jaw. You have a TMJ on each side of your head, connecting your lower jaw to your skull. These are intricate, immensely powerful, and surprisingly fragile joints. When injured, inflamed, or otherwise damaged, they can become your worst headache – quite literally. TMD (temporomandibular dysfunction) is a painful condition with a broad range of potential symptoms. Dr. Wood offers effective, conservative, non-surgical treatment with custom made TMJ appliances.
