I'm going to make my dentist feel bad
For what reason do you want to make your dentist feel bad?
He hurts me during my office visits.
You should be nice to your dentist. Dental procedures hurt. Be nice to him.
I deserve to hurt him without any pain.
You don't deserve to hurt him, because the pain that he inflicts on you is the kind that is meant to help you. You should be thankful that someone is willing to fix your teeth and not make their job harder.
