Disorders of Jaw Joints

The jaw joint is known as the Temporomandibular Joint (TMJ) and is located in the front of the ear canals which can be easily felt with your fingers. It is one of the body’s most used joints and is important in relation to chewing, talking and yawning. Any disorder of this joint can limit several bodily functions and cause pain.

​

Causes of TMJ Disorders
TJM disorders can develop by the loss of teeth which can alter the bite or grinding and clenching habits which cause abnormal pressure. Emotional or physical stress can induce grinding and clenching, creating pressure in the joint. Traumatic injuries like a fractured or broken jaw, degenerative diseases such as osteoarthritis and the poor design of dentures, bridges and fillings, can also contribute to the development of TMJ disorders. Careful diagnosis of the cause by your dentist is important.

Symptoms of TMJ Disorders
Each person is different and TMJ symptoms can become evident in many different ways. This may include limited jaw movement when trying to open or close the jaw. Locking of the jaw, clicking or popping noises from the joint, pain and discomfort when opening or closing your mouth are also common symptoms. Headaches, earaches or muscular pain due to inflammation from around the joint, or aching teeth can also become apparent
