A New Molecule May Make Cavities A Thing of the Past

Dentists may want to make note of a new molecule called Keep 32. It’s called that because the molecule seems to have the capabilities to help you keep all 32 of your teeth in your mouth and potentially make cavities — and maybe dentists — a thing of the past.
The chemical was designed by scientists in Chile who seemingly have a vendetta against 
dentists
 bacteria. In laboratory tests, Keep 32 was able to wipe out all the bacteria that cause cavities in about 60 seconds. The molecule targets the bacteria known as streptococcus mutans, which keeps dentists in business by turning sugar into lactic acid, which in turn erodes tooth enamel. Once the streptococcus mutans is eradicated, mouths stay cavity-proof for several hours.
