well there will come a time when brushing teeth will be a matter of life or death. but until that time theres always the lazy way out: mouth wash. btw. i do know that brushing teeth at night is better than in the morning cuz when your asleep at night and you dont brush ur teeth the bacteria gets all sexually enhanced or something like that and it makes your breath stink i read it in a dental magazine once while in the waiting room at the dentists
