A toothpaste called Theodent has recently hit the market, and it promises to strengthen the enamel of teeth by using a natural extract from the cocoa bean.

The substance, called theobromine, was discovered to be beneficial to teeth by a doctor in the 1980s – and he’s developed a fluoride free- toothpaste, which he claims works even better than the regular fluoride stuff we’re used to. (MSN.com)
