It's most likely happened to you before, after drinking a dyed sugary liquid (kool aid, or gatorade) your mouth turns the color of the drink. Same thing happens with some candy (now & laters = purple tongue! ). Is there a good way to get rid of the coloring stains fast? It seems like i always have to wait it out, even though it never takes a really long time. Can brush it off your teeth fairly easily, but you can't really get the coloring off of your tongue, or the insides of the lips. Brushing your tongue/lips doesn't work (and is just plain weird anyways), mouthwash also doesn't work.
