Unless you have a specific issue dentists offer mainly preventative care. The thing with preventative care is that you can never really prove what is working and what is not. Also, you can never really know when you've done enough. I think of it kinda like a car wash. You can pay extra for the fancy spray on waxes or you can just get a basic wash. How much does wax quickly sprayed on by a machine do for your car in the long run? Not much. But it makes you feel like you're taking care of your ride. Sub in teeth (a part of the body) for a car and they can charge almost whatever they like for shining bright lights in your pie hole.
