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?
Two temporomandibular joints 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 of developing a TMJ problem is higher 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, while for others it will continue to persist despite extensive therapy.
Diagnosis and Treatment
When evaluating for the presence of a TMJ disorder, an oral and maxillofacial surgeon 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 severe and persistent TMJ problems, the oral and maxillofacial surgeon may recommend a surgical procedure.
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 movements such as wide yawning and gum chewing, to practice stress reduction and relaxation techniques and to apply ice packs or moist heat as directed. As recommended, a patient should follow the oral and maxillofacial surgeon's or therapist’s instructions 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, stronger pain or anti-inflammatory drugs, muscle relaxants or anti-depressants may be prescribed
