Mouth Flora

A bacterium that lives on a tooth leads a fairly cushy life. All such a parasite has to do is hold on and the host (you) will bring it food several times a day. One of the reasons bad breath from infection from mouth bacteria is such a sexual turn off is that it is a sign of a weak immune system. A sweet-smelling mouth means genetic fitness. Even if you knock the bacteria out completely, they will be back within 12 hours. That is why you need to brush both morning and night to stay fully on top of them.
