Temporomandibular disorders (TMDs) are an extremely common group of conditions affecting the jaw joints, known as the temporomandibular joints (TMJs). This group of conditions are an extremely common cause of jaw pain which is typically localised over one or both the jaw joints/TMJs and often associated with other symptoms, including jaw joint clicking, grinding and jaw locking which can cause problems with common activities such as mouth opening, chewing, biting, yawning, laughing and kissing.
Typically, TMDs are caused due to trauma to the jaw due to extended mouth opening, following a visit to the dentist, chewing or biting down on hard foods like apples and meat. Other causes of TMDs include a direct blow to the face or inflammation within the jaw joint as well as osteoarthritis.
Jaw pain is usually associated with a TMD however other less common causes of jaw pain include ear, nose and throat problems, dental problems, neck problems and nerve problems. Rarely more serious conditions associated with the heart, blood vessels or brain amongst others can also be involved which is why prompt assessment is always recommended. Read more
