Temporomandibular Joint (TMJ) / TruDenta
The temporomandibular joint (TMJ) is a small joint located in front of the ear where the skull and lower jaw meet. It permits the lower jaw (mandible) to move and function.
TMJ disorders are not uncommon and have a variety of symptoms. Patients may complain of earaches, headaches and limited ability to open their mouth. They may also complain of clicking or grating sounds in the joint and feel pain when opening and closing their mouth. What must be determined, of course, is the cause.
What Causes TMJ Disorders?
Determining the cause of a TMJ problem is important, because it is the cause that guides the treatment.
Arthritis is one cause of TMJ symptoms. It can result from an injury, gum or pen chewing, jaw clenching or from grinding the teeth at night. Another common cause involves displacement or dislocation of the disk that is located between the jawbone and the socket. A displaced disk may produce clicking or popping sounds, limit jaw movement and cause pain when opening and closing the mouth. This may occur due to loosening of the ligaments which support the jaw structure.
The disk can also develop a hole or perforation, which can produce a grating sound with joint movement. There are also conditions such as trauma or rheumatoid arthritis that can cause the parts of the TMJ to fuse, preventing jaw movement altogether.
Treatment may range from conservative dental and medical care to complex surgery. Depending on the diagnosis, treatment may include short-term non-steroidal anti-inflammatory drugs for pain and muscle relaxation, bite plate or splint therapy, and even stress management counseling. If non-surgical treatment is unsuccessful or if there is clear joint damage, surgery may be indicated. Surgery can involve either arthroscopy (the method identical to the orthopaedic procedures used to inspect and treat larger joints such as the knee) or repair of damaged tissue by a direct surgical approach.
Once TMJ disorders are correctly diagnosed, your OMS can provide appropriate treatment to relieve the problem.
