I think my dentist hates me.

I've been having me treat me for a root canal and seems to be taking an eternity to finish. Every time I go in for more work it's always a temporary filling, a post, cleaning out more nerve material... It seems like it will never end. All of the nerve material is out of the tooth, so he no longer uses novacaine on me. It's a weird sensation - to feel him drilling and be aware of the vibration of it without being numb. All I can think of is that movie with Dustin Hoffman and Lawrence Olivier where he's drilling away and Dustin Hoffman is in agony...
