Arthrocentesis for Temporomandibular Disorders - Topic Overview

Arthrocentesis is done by an oral and maxillofacial surgeon, who uses needles to withdraw fluid from and/or inject fluid or medicine into a joint space. Arthrocentesis of the temporomandibular joint is used:

  • To treat painful and limited jaw movement (hypomobility) or disc displacement that has caused chronic, severe pain.
  • As a diagnostic tool, when there is a need to analyze joint fluid for signs of disease.

Arthrocentesis seems to work for people who have severe closed lock of the temporomandibular joint.1

Don't Fear the Dentist

John Gamba was 9 years old when a dentist failed to anesthetize a back molar properly and hit a nerve dead-on. The result was a lifelong fear of dentists that reached a peak in his 20s, when he stopped going to the dentist entirely. "I couldn't even drive by a dentist's office without getting stressed out," he tells WebMD. Gamba was 38 when a chipped back molar began to decay, eventually causing him constant pain.

Arthrocentesis is done using local anesthetic, with or without a sedative. Injection of fluid into the joint can serve to:

  • Wash (lavage) from the joint pain-causing chemicals created by the inflammation process.
  • Reduce painful pressure or contact between the disc and bone.
  • Enlarge the joint space, making it easier to manipulate the joint gently.

At the end of the procedure, corticosteroids or local anesthetic may be injected into the joint. This can be particularly helpful in cases of temporomandibular disorder related to rheumatoid arthritis.

After the procedure, nonsteroidal anti-inflammatory drugs (NSAIDs) are used to control pain. And jaw exercises are started during recovery.

Only 18.5% of Americans never floss. You are missing out on a simple way to make a big difference in the health of your mouth. Regardless of how well you brush, plaque still forms between your teeth and along your gums. Floss removes food trapped between the teeth and removes the film of bacteria that forms there before it turns to plaque, which can cause inflamed gums (gingivitis), cavities, and tooth loss. Try flossing just one tooth to get started.
