Then get Simple DS Series Vol. 34 THE Haisha -- and pay D3 to let you be inhumane! For some reason, IGN has compiled a large gallery of D3's Japan-only budget torture game, showing all kinds of ... dental procedures ... and even some of the nightmarish implements you, as THE Dentist, will have access to.
For a cheap game about an extremely unpopular subject, we're kind of surprised by the effort shown here. There are many different kinds of ... tooth issues on display here, and both 2D and 3D representations of the offending teeth. The whole thing actually looks good.
