New chemical makes teeth 'cavity proof'

Smiley Bone
The chemical was designed by dentists in Chile, and wipes out all the bacteria that cause cavities in just 60 seconds in tests. The chemical could be added to any current dental care product, turning toothpaste, mouthwash and chewing gum into 'super cleansers' that could get rid of the underlying cause of tooth decay. The chemical targets 'streptococcus mutans', the bacteria that turns the sugar in your mouth into lactic acid which erodes tooth enamel.
