How an NTI-tss works
This is a simple demonstration of the efficacy of the NTI-tss device.
A) Begin by gently biting on the moon portion of your fingernail, using your central incisors. Only be forceful enough to create slight discomfort.
B) Now attempt to use the same amount of force, but this time bite with a canine tooth on the same spot of your fingernail as you did with the central incisors.
What happens? Biting with the canine tooth is suddenly more painful than with the incisors… Why?
The incisor teeth are intended to not only incise food, but to be “hardness monitors” of what you’re biting into. They are under your control and tell you if something will be to hard to chew.
The canine teeth are designed for grasping and pressing into what it is that you’re trying to hold on to (carnivores specifically use the canine teeth for this purpose). The intensity of muscular activity created once the canine teeth have been engaged is under less voluntary control. In fact, the message to the brain is: “We’ve opened our mouth to grab something and have caught it…hold on!” The contacting of canine teeth encourages jaw clenching!
