I think it really is genetic or at least individual to each person. I brush my teeth twice a day. I floss and/or brush lightly after eating. I have very healthy gums and almost no plaque buildup. My dentist told me I don't need to get the professional cleaning that she tries to sell everyone because my teeth are clean and my gums healthy. But then I get all these cavities and I can't do anything against them and my dentist is as frustrated as I am! My Mom has the same problem. And my Dad never had a cavity. It's all very unfair.
