Trapped like a tiny piece of broccoli in the crevice between videogames and dental hygiene, Tooth Invaders was one of the first attempts at putting forth a positive agenda in digital entertainment. The message here was that brushing your teeth was not only a good idea, it was a matter of life or death. In the game, a hangman-shaped avatar used a rake-like toothbrush to eliminate bits of plaque, which looked an awful lot like asterisks. The playing field was a set of Tony Robbins-sized chompers, all uniformly coffin-like. The sad victim you were trying to save had only eight teeth left. The game is mostly remembered from its Commodore 64 incarnation, but we remember playing it on the even lowlier Vic-20, where the teeth were even blockier, the decay of teeth even more dire. Ironically, we spent so much time playing Tooth Invaders as children that we neglected to brush or floss for weeks on end. We wear wooden falsies to this day.
