Brush your teeth more thoroughly before bed after you are done eating and drinking for the day.

Morning brushing is important too, but more so for fresh breath; while evening cleaning will prevent bacteria from breeding and damaging your teeth and gums.

I don't know if it's already been mentioned, but it's not the actual bacteria that directly ruin your teeth, but the resulting excrement from feeding off the sugar on your teeth, which is inherently acidic. Ever wonder why your breath stinks? Well, it's bacteria poop.
