Before, brushing right after eating removes whatever that thing on your teeth is that makes them durable (enamel?).
Sometimes before, sometimes after. Never directly after eating though, usually like an hour after.
after, because you'll only make your teeth greasy again by doing it before.
After is now leading the polls. So the real question was the statement above made about enamel true and how it decays meaning it is bad for you to brush after breakfast?
Before and after.
Usually I'll brush really quickly after I wake up just for my own satisfaction, then again properly a bit after eating...
I used to brush before as that is what i have always been taught to do.
But now, i brush after, i find doing so much easier.
once I've suited up and blinged out just before I leave for another busy day
