The Evolution of Cavities – Phenomena: The Loom

Interesting article on S. mutans which causes cavities.
Wonder what are the 148 unique to human microbiome genes that were picked up.

I doubt that removing S mutans will be an entirely good idea though, it will create a void for another species to exploit and who knows what diseases worse than cavities will prevail
