dentists lie all the time. my dentist said, "see you next year." well, i didn't see him. or his family, or his whole clan, tribe, or people. and you know why? because he lied.
i don't think it's necessarily the money that makes them want to pull your teeth. it's more the prospect that once they've collected fifty, they get 10% off cat food at walmart. them cats are not cheap to care for.
