Getting a tooth pulled is a much much worse procedure than a simple filling. I'd probably opt for 100 fillings before signing up for getting a tooth pulled.
the grinding/taste/vibration/experience of a filling is much worse for me than the experience of an extraction.
I don't know if that's rare or not -- but I have a very real aversion to the experience of dental grinding equipment, and that stuff tends not to get used much if at all during extractions.
