for how long should i brush my tooth?
until your gum bleed
For as long as it takes to drive from one end of Alabama to the other.
No way near as long as we were told. So much fucking false information.

I read the instructions on an electric toothbrush and it recommends 30 seconds of brushing per quadrant, making sure to brush a variety of surfaces within that quadrant.
