When you clench and grind your teeth at night, each tooth sends electrical signals to the central nervous system, then the brain, and last, to the chewing muscles of the jaw. Studies have shown that humans clench and grind for 2-6 hours nightly. Intensity is the only variable. Humans have been measured up to 900 PSI (pounds per square inch). Eating is only 68 PSI. As you can see, the muscles of the jaw are simply overworked at night. Stop the muscle use and “TMJ” symptoms dramatically improve. With less electrical firing to the brain, the muscles relax and the brain isn’t being bombarded. TMJ Orange County Ortho-Stop prevents the back teeth from making contact so that there are minimal firings. If you can’t make contact, the teeth can’t fire. A night guard is minimally effective because the back teeth do contact. Ortho-Stop is scientifically sound.
