New Molecule Can Cavity-Proof Your Teeth

Say goodbye to cavities: Two researchers have discovered a new molecule that can kill cavity-producing bacteria and even make your teeth cavity-proof for hours, just by staying in your mouth for a full minute. The scientists named the molecule Keep 32, after the 32 teeth humans have, and they say it can be added to toothpaste, mouthwash, or even candy and gum. They hope to have it on the market in 14 to 18 months, Gizmodo reports. (More cavities stories.)
