Ah, that makes sense. I suspect dentists get a lot of requests like that. I am always pretty blase about dental work, so honestly general anesthesia didn't occur to me as an option, but I might have preferred that had I thought of it. (Also, apparently I was just more tolerant of the stuff they did give me--my sister got the same treatment soon afterward, and she was knocked silly and doesn't remember any of the procedure. But she's a lot skinnier than me ...)
