The Prevalence of Temporomandibular Joint Problems
According to the National Institute of Dental and Craniofacial Research (NIDCR), temporomandibular joint disorders (TMJ), also referred to as temporomandibular disorders (TMD), are the most common source of chronic facial pain and jaw dysfunction. It is estimated that more than 10 million people in the United States are affected by temporomandibular joint problems.
What is the Temporomandibular Joint?
There are two temporomandibular joints that connect the left and right sides of the lower jaw to the temporal bone. Both joints and their associated muscles, ligaments and tendons work together to allow for all manner of oral function as the jaw moves up and down, front to back and from side to side. Containing a shock-absorbing, soft disc that sits between the rounded condyles of both sides of the lower jaw and the corresponding concavities in the skull’s temporal bone, the TMJ makes chewing, speaking, yawning and all jaw movements possible.
Since the TMJ is a joint with both up and down hinge-like movements, as well as side to side and front to back sliding motions to perform, it is often considered one of the most complicated joints in the body and one of the most difficult to treat when problems arise.
Types and Symptoms of TMJ Disorders
TMJ disorders can fall into one or more of the following three categories:
The risk for developing a TMJ problem is greater in the presence of long-term teeth grinding or bruxism, a jaw injury or various types of arthritis such as rheumatoid arthritis and osteoarthritis. Furthermore, the manifestations of a TMJ disorder can vary from person to person with a wide range of symptoms possible, including earaches, ringing in the ears (tinnitus), headaches, back and neck pain, vertigo, muscle spasms and joint tenderness as well as jaw pain, popping or grating sounds with jaw movement, jaw locking and limited jaw movement. For some people a TMJ disorder can be resolved within a relatively short period of time, while for others it will continue to persist despite extensive therapy.
Diagnosis and Treatment
When evaluating for the presence of a TMJ disorder, the dentist will perform a thorough clinical assessment of joint symptoms and function. Special radiographic imaging and other diagnostic tests will be ordered as needed. The treatment of a TMJ disorder may include oral appliances such as night guards or stabilization splints to alleviate strain on the joints. Other types of therapy may include steroid injections, occlusal adjustments as well as orthodontic or prosthodontic treatment to improve occlusion. In cases of persistent and serious TMJ problems, surgery may be recommended.
Methods of self-care can be helpful in alleviating some of the symptoms of a TMJ disorder. Patients are typically advised to eat soft foods, avoid extreme jaw movement such as wide yawning and gum chewing, to practice stress reduction and relaxation techniques and applying ice packs or moist heat as directed. If recommended, a patient should follow the dentist or therapist’s instruction for gentle stretching exercises. The short-term use of over-the-counter, non-steroidal, anti-inflammatory drugs and pain medications may provide relief. If not the dentist or physician may prescribe stronger pain or anti-inflammatory drugs, muscle relaxants or anti-depressants.
A TMJ disorder is a condition affecting the temporomandibular joints, which connect the jaw to the skull. These disorders can cause jaw pain, headaches, clicking sounds, stiffness, and difficulty chewing or speaking comfortably.
TMJ disorders can develop from several factors, including teeth grinding, jaw clenching, stress, bite misalignment, injury, arthritis, and chronic muscle tension.
Common symptoms include jaw pain, headaches, facial soreness, ear discomfort, popping or clicking sounds, limited jaw movement, and difficulty chewing.
Yes. Stress often contributes to jaw clenching and muscle tension, which can increase strain on the temporomandibular joints and worsen symptoms.
Treatment depends on the patient’s specific condition and symptoms. Conservative approaches such as custom oral appliances, bite evaluation, and muscle tension management are commonly used.
Yes. Chronic grinding and clenching can wear down enamel, create fractures, increase sensitivity, and contribute to jaw strain over time.
You should seek professional evaluation if jaw pain, headaches, clicking sounds, or difficulty chewing persist or interfere with daily activities.
Yes. TMJ dysfunction frequently contributes to tension headaches due to strain in the jaw and facial muscles.
Most TMJ treatments are conservative and noninvasive. Treatment is designed to reduce pain and improve comfort rather than create additional discomfort.
