Theodent is the absolute best toothpaste formulation on the market, the world's only absolutely safe alternative to kinds of toothpaste containing fluoride. It took more than 30 years of continuous clinical studies to create a unique revolutionary formula Rennou, a proprietary blend of cocoa extract and other minerals, which is unique worldwide. This active ingredient in the toothpaste increases the size of enamel surface crystals, making teeth less susceptible to bacterial acid demineralization. All components of Theodent are of natural origin, therefore completely harmless to health, even if accidentally swallowed. The prestigious G.R.A.S. status confirms the complete safety of the product according to the standards of the FDA.
