Now, before we get to it I need to point out one thing. Dentists are evil, sadistic people anyway, ranking just one step under clown in the great chart of demon hell spawns bent on our demise. They all take delight in out pain and suffering while distracting us with a Nitrous buzz and a cute picture of a kitten pinned to the ceiling. When one blindly opens themselves to them outside of a casual cleaning is when real disaster can happen.
