The first little gem I've discovered is disposable toothbrushes. My roommate gave me a pack of Plackers Flash Disposable Toothbrush in my stocking for Christmas. Six come in a package, and they are individually wrapped which makes them portable. Although they aren't the ideal way of brushing one's teeth, they are perfect for times where it's just not possible to break out your toothbrush and toothpaste and brush away that coffee breath. You shouldn't go as far as to only use disposable toothbrushes -- that just wouldn't be hygienic -- but in terms of convenience and getting that those teeth feeling much less fuzzy, these mini toothbrushes do the trick.
