The amount of x-rays done varies with the treatment you are receiving. Regular dental check-ups come twice a year for me. I get an x-ray of both sides top and bottom once a year. If you change dentists, the new dentist will want a complete set of x-rays, despite with the prior dentist did.
I don't think it's good to get a set of x-rays just because you are going in for a normal cleaning and check-up at six month intervals.
I am not a passive patient myself. Whether it be the dentist or the doctor, I want them to tell me what they are doing, why they are doing it, etc. If I believe it isn't necessary, I tell them or request additional information. Some dentists are quite radical. I once had to change dentists due to a new insurance plan, and was told during a simple routine check-up that my jaw needed to be broken and all my teeth reset because my bite was "off"!! Mind you, I was 53 at the time, and never had problems with my "bite".
I listened to her bizzare annalysis and then went home and called the head dentist at their office with my concerns and asked him to pull my records and take a look. He told me that I needed no such radical invasive procedures. (which I certainly already knew) When I went back in six months, she was GONE.
Other dentists have tried to convince me that old crowns need to be replaced. My answer to them was, no way. There was no justification, they just wanted to bring in the money. Even if you have dental insurance, crowns still cost us around $425.00 locally.
