Thanks everyone for your responses. I've got an appointment on April 5th with another dentist so we shall see then.
I don't drink anything but water, milk and tea (no sugar). I very occasionally will have a latte (once, twice a month at most) but I don't remember the last time I had a coke or a cup of juice. My kids are deprived too. :) But that being said, my husband drinks nothing but cokes and has never had a cavity in his life, no lie.
Sharon, thank you for your info. I'm assuming the woman that cleaned my teeth was licensed in whatever way the state requires. I'm not questioning that in any way. I just called her an "assistant" for lack of a better word. The dentist I saw did not offer to show me the xrays, but I didn't ask either as I figured I wouldn't be able to tell one thing from another. When I did ask how this could happen, she didn't offer up any kind of explaination other than it had been so long since I was seen.
