Play a dentist in this game that brings you up close and personal with the inside of people's mouths. You start the game staring into a person's mouth. Cavities start leaving little green specks of decay on teeth, and you have to use your sprayer to clean them off as fast as you can. Try to only use the sprayer on dirty teeth—you don't want to waste the water on teeth that are already clean. You get a bonus in your score for finishing quickly and accurately. If you let a tooth go for too long, it will get infected and eventually need a root canal or to be removed completely.
