< * The teeth are never in contact except during mastication and swallowing, more rarely during speech. * When they touch, the message they use to send is rather a tactile (non painful) one than an algic one. The more the teeth are stimulated the more intense the messages are. * All these messages rise up to the brain through the two trigeminal nerves (right, left)
*Unfortunately some anxious, introverted or frustrated persons clench their teeth independently from these normal activities : that is then called a parafunction.
*Disturbing and disabling pains and/or troubles may then occur, especially when intense or persisting stressing conditions prevail.
*95% of people are sure that the teeth are only "pieces of bone set up in the maxillar bones and that generate pains". Confronted to physiological laws, it's a wrong belief ! *Physicians admit that the teeth might provoke tendinitis (Achilles tendon).
Based on anatomical and neurophysiological data, this website tries to help the reader in actualizing his or her knowledge about teeth, masticatory muscles and jaw joints, inside the oral sphere. Remote and upsetting pains as well as unexpected troubles may appear when a parafunction (strong teeth clenching) exists.
When a person "strongly and often clenches her or his teeth", it will be useful to reconsider a possibly too hasty diagnosis of fibromyalgia or chronic fatigue symptoms.
That’s also an hope of this website…
We owe a debt of gratitude to Professor Albert Jeanmonod who coined the French expression "crispation des mâchoires dents serrées”, which translates as “clenched jaw with masseter spasms”. The phrase permits a precise differentiation with “grinding”. When one speaks of bruxism, most people think we speak simply of obsessive “grinding of teeth”. Jeanmonod’s expression permits a clearer explanation of the difference between grinding and clenching. It is primarily the latter that is the source of the specific pains and associated discomforts that are here more fully developed.
