If you have sensitive teeth, you need MINERALS! The majority of people in the US have some sort of vitamin or mineral deficiency. Sensitive teeth mean enamel is wearing and your enamel is an extension of the bone underneath. Bones need minerals. Look for products, like ours, that are highly mineral based. All of our formulas use calcium carbonate and it’s found in almost all desensitizing formulas and it’s natural and edible. Direct application of tooth powder, containing no binders or emulsifiers (like all pastes), means you get the best ingredients to directly apply, without cutting through glycerin and surfactants.
