Headaches, neck, and face pain are just a few of the symptoms experienced by millions of Canadians suffering from TMJ/TMD. The exact cause of this pain varies from patient to patient, as does the symptoms and severity of those symptoms. When you do experience any sort of face pain, your temporomandibular joints (TMJ) is usually looked at first. Your TMJ connects your lower jawbone to your skull and is responsible for giving you the ability to chew, talk, yawn, swallow, and more. Pain in the jaw can restrict movement and can be extremely unpleasant, so when you begin experiencing any sort of discomfort you should get it checked right away. Causes of TMD can be due to a combination of factors including genetics, arthritis, jaw injuries.
