Dentists in Chile have created a new chemical that could make human teeth 'cavity proof' - and do away with the need for visits to the doctor forever. The molecule has been called 'Keep 32' - after the 32 teeth in a human mouth. The chemical wipes out all the bacteria that cause cavities in just 60 seconds in tests.
