Trauma

I hate the dentist. No really, I want to hurt him. Any advice on how to either do it, or how to stop myself from doing it??

Well, this is one of those things where your problem with someone else probably originates within yourself. I don't have a detailed history of your oral health, but I'd wager that you're not brushing 2 or more times a day and flossing daily (correct me if I'm wrong). So my advice is to start doing exactly what your dentist tells you. Then you can be smug and have the attitude of "Ha! No more inflicting of pain on me by you!" And, along with the physical pain, your emotional pain will disappear.

If that doesn't work, I suppose you should consider an anger management class. The bottom line is that you shouldn't try to hurt your dentist for two reasons: 1) it's illegal; and 2) dentists are way better at inflicting pain than the rest of us could ever hope to be.
