It's a new toothpaste called "Theodent", and it's made of a substance proven in clinical trials to strengthen teeth and regenerate enamel.
A doctor (Tetsuo Nakamoto) found "Theobromine" in chocolate in the early 80s. Since then, he worked to get a patent and put that substance into a toothpaste.
One expert explains: "Theodent is a fluoride free toothpaste. Rennou... the active ingredient, works better to re-mineralize the surface of human teeth."
Clinical trials show the positive effects of Rennou on a tooth.
The substance is safe for children to swallow because it is a derivative of chocolate and is all natural.
Traditional Theodent is mint flavored, but the kids version is chocolate. For more information on the product go to Theodent.com. The toothpaste can be purchased there or at Whole Foods Markets.
