Brentwood TMJ DentistJoint Vibration Analysis, or JVA, is a test done at our Brentwood office to detect vibrations in your temporomandibular joint (TMJ). The TMJ is the joint of your jaw on the left and right side, and it’s used to open and close your mouth.

The device literally looks like small headphones, and is placed on your left and right TMJ joints — right next to your ears. This device can detect if there is any vibration when you open and close your mouth and how severe it is.

What causes the joints in your jaw to vibrate?

A small cartilage disc sits in the joint of your upper and lower jawbone that is supposed to be attached to your lower jawbone and slide along with it as you open and close your mouth. This disc prevents your two jaw bones from grinding on each other. If this happens, the disc can get bunched between the jawbones when opening and closing your mouth.

There are many reasons that can cause the disc to become damaged or detached from the lower jawbone, such as trauma, orthodontic work, arthritis, clenching and teeth grinding.

Other symptoms of a vibrating TMJ include popping, and/or lock jaw.

What happens next?

After competing your JVA testing, we will interpret your vibrations and go over the results with you. If your TMJ appears to be functioning normally, you indeed have a healthy jaw. However, if we notice signs of disorder, we may recommend a TMD treatment plan. This could include a custom made oral appliance to keep your jaw in a healthier position during sleep, dietary changes, certain lifestyle modifications such as stress reduction techniques, or alternative treatments. In all cases, we will help you choose the most conservative treatment options available, avoiding surgery or other more intensive procedures unless absolutely necessary. We are committed to helping you manage your TMD to alleviate discomfort, restore function, and empower you with education about your oral health.
