Bullshit, but necessary. There is a lot of stuff that can go wrong with your teeth, but aside from putting in fillings and fixing really bad things with your teeth, it's largely useless and should be some sort of sub field. Basically like >>7908770 says, it should be something that you get referred to because of specific things that might be wrong with your teeth that you discuss with your general doctor.
As it is, it's like going to your doctor and your doctor is always trying to convince you to get your tonsils taken out or your appendix removed, just in case. There should definitely be some sort of outside recommendation/examination before you go to the dentist just so they can make bucks drilling into imaginary tiny dents in your teeth.
It's really a problem with dentists than dentistry.
