We made a Sensitivity Blend of our Remineralizing Tooth Polish! The ingredients include Calcium Bentonite Clay, di calcium phosphate, Calcium carbonate, L-arginine powder & Trace minerals. New studies have shown that, when combined with calcium, Arginine has been clinically proven effective in reducing caries & treating dental sensitivity. New research from the University of Michigan suggests that it also may break down dental plaque. This could potentially help millions of people avoid dental decay & gum disease. Our saliva contains alkali-generating bacteria. Arginine was discovered to be the key substrate in saliva that these pH-raising bacteria metabolize to produce base (i.e. alkali). Balancing the pH in our mouths is key to remineralizing. L-Arginine can also be requested in any of our other toothcare products! :) 1Oz & 3Oz Sensitivity Blend Arginine Remineralizing Tooth Polish Organic, Vegan, Non-Gmo
