Dentists can be complete crooks though. All my life I went to two dentists. Both were pretty good, and I had cavities pretty rarely. Later, my parents had to switch insurance, so we went to another dentist with a much nicer office. He takes a quick look at my teeth and says, "Oh yeah, looks like about eight cavities. We should drill them etc etc" My parents are shocked and take me back to our most used old dentist for a second opinion. He examines me closely with a pick and tells us the other guy is full of shit, and that behavior is really common in dentistry.
