I just got back for a cleaning and repair a filling that came out. I don't really mind the novacain shot. But, when he is drilling the tooth and you start to feel the pain. Woops, not enough novacain. I do mind that. This has happened to me the last two times. I mean the whole area felt numb. I start to think I am making up the pain in my mind. No, way I can't make up that kind of feeling.
