Okay, enough of the Public Service Announcement voice. Sorry, we just couldn't keep that going - we're not highly-trained military personnel. But Toothsavers is indeed a real app, created by the Ad Council, designed to teach children ages 3-6 healthy brushing habits. The game features 10 cartoon teeth, which are unlocked by brushing two minutes twice per day, as well as a parents' section to help chart their children's progress. You can check out the game for free online, or download it (also free) from the iOS and Android stores.
Ads promoting healthy teeth habits sure have come a long way since the Cavity Creeps.
