What is TMJD?
Temporomandibular joint disorder (commonly abbreviated as TMJD) is a painful and uncomfortable condition caused when one or both TMJ joints become inflamed due to misalignment or injury. This occurs when the jaw is out of its natural place or teeth are crooked or crowded. The most common cause of the TMJD is bite malocclusion more commonly known as a bad bite. When this occurs, the muscles of the jaw are strained because they are forced to hold the jaw in an unnatural position. Symptoms of the disorder are similar to other health conditions and are often misdiagnosed.
Long-term TMJD can cause arthritis and chronic pain for patients if not treated. The exact number of people affected by TMJD is unknown, however, the National Institute of Dental and Craniofacial Research estimates that about 10 million Americans suffer from the condition.
