Tooth Terror is a hilarious 2-3 player card game in which you assume the role of a particularly nasty dentist. You score 'Pain points' by performing treatments. These vary from moderately (Drilling) to excruciatingly painful (Root Canal). Try to make your treatments as painful as possible in order to collect as much Pain points as possible.
To hinder your opponents, you play cards that make their treatments less painful (Anesthesia, Sterile equipment). Of course you can also make your own treatments more painful by playing cards like Blood loss.
The game ends when there are no more cards to draw from the shared deck. Everybody compares their points and whoever has inflicted the most pain upon his patients is the winner of Tooth Terror.
