What is the difference between tmj and tetanus?

Answer 1

There are nearly no similarities, at all, with the exception of location. Tetanus is a disease that can cramp and lock your jaw muscles, preventing normal eating.

TMJ is an abbreviation for your jaw joint, just under your ear. TMJ stands for 'temporo-mandibular joint. When people say, "I have TMJ", they really mean that they have a TMJ disorder which can range from the TMJ popping when the mouth is opened or closed all the way to an actual dislocation of the TMJ when the mouth is opened or closed.
