TMJ is short for “temporomandibular joint”. This important joint attaches your mandible (lower jaw) to your skull. The TMJ acts as a universal joint and enables your mouth to open and close, and moves from side to side when chewing. Muscles surrounding and attached to the TMJ control its position and also control jaw movements during talking, chewing and yawning.
Many people suffer from disorders on one side or both sides of the TMJs, or in the surrounding muscles and tissue. These disorders are known as Temporomandibular joint dysfunction (TMD). Symptoms can include pain, clicking and reduced jaw function. There is often referral pain or a blocked feeling in the ear.
Successful treatment for TMJ problems is usually achieved with simple measures such as heat, soft diet, topical pain killing gels or pain killers. Sometimes a bite splint or plate is constructed, and worn at night to reduce joint loading and reduce pain.
Restriction of opening or locking may require a joint wash out or arthrocentesis and manipulation to help reposition a displaced disk. Occasionally surgery may be required to treat arthritis of the joint.
TMJ splints are a commonly used treatment option for people with TMJ disorders. The splint will assist with keeping your teeth slightly apart – this helps reduce pressure on your joints and the muscles surrounding your jaw area. This enables the jaw to relax and will help relieve discomfort.
These splints are custom-made to fit over your upper or your lower teeth. An impression of your teeth will be taken, then the bite splint will be molded from acrylic to fit your teeth.
Your oral surgeon or dentist will tell you how often you should wear your splint, and when you should wear it. Splints can be worn at night or during the day.
