@indigomoth - That's why flossing is better than brushing your teeth. I've even heard a dentist say that toothpaste is not necessary at all, as it is the physical action of removing bacteria with the brush and the floss that is important, and a mouth wash will prevent them from growing back.
I can't wait until they finally manage to develop the bacteria that they have been promising for a long time, that will make teeth cleaning and dental hygiene a thing of the past altogether.
It's a type of bacteria which inhibits the bacteria which harm teeth, without harming you as well.
If they ever manage to develop it, you pretty much would get infected by the bacteria when you develop teeth and never have to worry about them again.
