Mouth opening exercises are mainly suggested in patients suffering from lockjaw (trismus). These exercises help to relax the muscles and create movement in the jaws. These exercises prevent pain and inflammation in such cases. These exercises are of various types such as active jaw exercises, passive jaw exercises, chin tucks, and neck stretches.
Trismus and Its Clinical Evaluation: An Overview
Trismus results from excruciating spasms of the muscles surrounding the jaws. This causes limited mouth opening.
