Not really a scary book but it really gave me the creeps. In the book "Marathon Man" when the author described the dental prodedure the "dentist" used as torture.

Gave me chills. I think of that every time I'm in the dentist's chair.

The whole scene starts in the book where he's in the bathtub. He hears someone in his apt. He's kidnapped and is taken to the "dentist" for interrogation.

Here's a clip from the movie version (it's a pretty long one):
