Although very busy every day, the masticatory muscles have reacted, like the majority of our muscles, to permanent over-activity: they become sensitive, even painful. Most people cringe or clench during sleep and / or during the day. In these people, the contraction of these muscles can be up to 20 times more intense than in people who do not do each other. This muscular hyperactivity, over time, can trigger symptoms such as headaches, muscle contractions in the shoulders and back.

As a result, dentists often find excessive dental wear and joint problems in the jaw.

* Offset bruxism or jamming of the jaws is very common and involuntary.
