Trismus is also known as “lockjaw”. People who have Trismus will have reduced ability to open their mouth or feel pain when opening mouth. If not treated promptly and properly, this hidden disability can seriously affect recovery, health and quality of life.


The TheraBite® Jaw Motion Rehabilitation System™ is a portable device that is effective for treating Trismus. It helps you to restore movement and flexibility of jaw, joints and connective tissues by utilizing repeated stretching and passive motion. It is clinically proven to increase mouth opening by around 1cm after a 6-10 weeks of stretching program.
