TL;DR

The long battlefield in the fight against cavities has shifted recently with the shipping of Lumina toothpaste. What is behind this shift? A small engineered bacterium, developed by Lantern Bioworks, called S. mutans bacterium which aims to put an end to cavities not by eliminating sugar (who wants that?), but by cleverly re-engineering the very bacteria that cause decay to produce harmless ethanol instead of corrosive lactic acid.

It’s a millennia old problem with a modern solution.

More after the break.
