There is a surge of new toothpastes and toothpowders on the market that promote the use of Hydroxyapatite (HAP) or Nano-hydroxyapatite (nHAP) as the latest and greatest remineralizer and enamelizer. But what is it? And is it safe?

What is "Living Clay”?
Living clay is a very unique type of clay associated with biological life. It possesses some amazing qualities including the ability to undergo chemical changes, both absorb and adsorb (release) substances, and interact with its surrounding environment. Plus it contains a range of micronutrients and micro-organisms. Living clay has been linked to the origin and evolution of life, as it retains information, exhibits self-organization, and interacts with organic molecules.
