A new chemical molecule that kills the germs that cause cavities could be added to tooth paste in a years time.  The molecule has been called ‘Keep 32’ developed  by dentists in Chile. A single .5mg application kills all the bacteria that cause cavities in just 60 seconds in tests.Keep 32 could keep you cavity free

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 works by killing ‘streptococcus mutans’, the bacteria that turns the sugar in the  mouth into lactic acid. The lactic acid in turn erodes tooth enamel and promotes decay.
