It's here!  Chocolate toothpaste!

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.
