The temporomandibular joint – the TMJ – is the joint between the jaw and the temporal bone of the skull. The TMJ is responsible for jaw movement and allows chewing, speaking, and yawning. Temporomandibular disorders, or TMD, refer to a group of conditions characterized by pain in the jaw area and limited jaw movement. TMD can be caused by problems in the joint itself or in the muscles surrounding the joint. Joint problems can include arthritis, inflammation, and internal derangements. When the problem is in the muscles, the condition is called myofascial pain syndrome. Myofascial pain syndrome is very common and can occur in patients with normal temporomandibular joint function. The syndrome is characterized by the presence of hyperirritable points located in the skeletal muscles called trigger points. A trigger point can be felt as a lump of muscle with a firmer consistency than normal. Palpation of trigger points can evoke pain in a different location. This is called referred pain. Trigger points develop as a result of muscle overuse. Typically, the chewing muscles are overused when patients unconsciously clench or grind their teeth excessively during sleep. The medical term for this condition is “nocturnal bruxism.” A trigger point is composed of many contraction nodes where individual muscle fibers contract and cannot relax. The continuous contractions of the sarcomeres compress the local blood supply, resulting in a lack of energy in the area. This metabolic crisis activates pain receptors, generating a regional pain pattern that follows a specific nerve pathway. The pain patterns are therefore consistent and well-documented for several muscles. Trigger points in the masseter muscle refer pain to the cheeks, jaw, upper and lower molars, eyebrow, inside the ear, and around the TMJ area. Trigger points in the temporalis muscle are also associated with headaches and toothaches in the upper teeth. The main culprits of myofascial pain in the TMJ area are the pterygoid muscles. Trigger points in the medial pterygoid muscle refer pain to the TMJ region in front of the ear, inside the mouth, and the upper outer neck. They can also manifest as a sore throat and difficulty swallowing. Trigger point pain in the lateral pterygoid can be felt in front of the ear and at the top of the jaw. Treatments aim to address bruxism, relieving muscle spasms, and releasing trigger points. Treatment options include: Therapies: stress management, behavioral therapy, biofeedback—to encourage relaxation. Nighttime mouthguards: occlusal splints and mouthguards—to protect the tooth from damage. Medication: pain relievers, muscle relaxants, and Botox injections. Trigger point release techniques, such as dry injections and "spray and stretch."
