What the TMJ is
The temporomandibular joint is the hinge where the lower jaw meets the skull. A disc of cartilage sits between the two bones, and the muscles that close the jaw attach to the mandible. Jaw pain, clicking and locking usually come from this joint or those muscles — not from the teeth themselves.
This record sits in East Patchogue, NY, so the joint problems patients bring here are the same ones the rest of the NY directory deals with — but the treatment route depends on what this particular office records.
