Best Dental TMJ Service in Joplin, MO
The temporomandibular joints, called TMJ, are the joints and jaw muscles that make it possible to open and close your mouth. Both of your TMJ joints are located on each side of the head. They work together when you chew, speak or swallow and include muscles and ligaments as well as the jaw bone. They also control the lower jaw (mandible) as it moves forward, backward and from side to side.
Each TMJ has a disc between the ball and socket. The disc cushions the joint while enabling the jaw to open widely and rotate or glide. Any problem that prevents the muscles, ligaments, discs and bones from working properly may result in a painful TMJ disorder.
Causes of TMJ Disorder:
Dislocation of the disc in the joint
Deformities of the jaw
Inflammation, infection, arthritis of the jaw area
Injury to the jaws
Muscle strain from chewing or teeth clenching and grinding
Symptoms of TMJ Disorder
Popping or grating sound when you open or close your mouth
Headache or pain in your jaw, ear, neck or face
Pain or swelling of the jaw muscles
Trouble opening or closing your mouth
Locking of the jaw (open or closed)
