HOW YOU CAN PREVENT HEAD-PAIN RELATED TO TEETH CLENCHING AND TEETH GRINDING                                                                           Dr. Marvin Mansky, New York Dentist tells you how Many types of head pain have a common cause.  The cause is the sleep disorder of intense and prolonged teeth clenching.  It's perfectly normal to clench your teeth when you sleep.  We all do from time to time - during normal sleep cycles. What happens when you clench your jaw muscles up to 14 times more intensely than normal?   It results in tension headaches, migraine headache pain, TMJ face pain, eye headache, sinus headaches, menstrual and hormonal migraines, neck pain, morning and nighttime headaches and also teeth grinding (Bruxism). Prolonged and intense teeth clenching causes significant muscle contractions and nerve bundle distortions, mainly of the temporalis muscles on the sides of the head, as shown in the diagram to the right.  The location of the pain depends on where the teeth are positioned when clenching.   How People Describe Their Head Pain   Google searches from all over the world to this site indicate the great variation in type, location and quality of head pain searched for by people with suffering with this problem.  The following is a much abbreviated list:     Head pain types:  Tension headaches; migraine headaches; TMJ face pain; eye headache; sinus headaches; anxiety and stress related; menstrual and hormonal migraines, neck pain, morning and night time headaches. Head pain location: Headaches; face pain; TMJ pain; ear pain; neck pain: back head pain, upper neck, lower neck, right neck, left neck and side neck pain; chronic neck pain, and even a pain in the neck; shoulder pain Head pain quality: Severe; constant, chronic, sharp, daily, dizzy, pressure.   How Head Pain Can Be Prevented   It may sound simplistic but the way to prevent clenching related head pain is to prevent clenching.  A dentist named Dr. James Boyd was a migraine sufferer for 12 years.  He made it his quest to prevent migraines for himself and his wife.  Dr. Boyd discovered that when the cuspid teeth (also called canines or eye-teeth) come into contact with the teeth of the opposing arch it triggers of clenching.    Eventually Dr. Boyd came up with a dental device he named the NTI-tss (NTI).  It functions to prevent teeth clenching.  By stopping intense clenching it prevents clenching related tension headaches, migraines, TMJ face pain, sinus pain, neck pain, jaw clicking, sleep and morning headaches as well as teeth wear and teeth breakage caused by teeth grinding.    The remarkable success of the NTI, the only FDA approved dental device for this purpose, has allowed us to offer a money back guarantee if it does not succeed.
