One and a half cavities per year..? Is that normal? I'm pretty scared if it is...I haven't had cavities myself as far as I know (one may not be aware of their cavities but seeing that I have been seeing dentists and even had my wisdom teeth removed recently I probably don't have anything visible)

I am reading up on dental caries right now because I don't want to ever get them...does anyone have relevant information?

Edit: Looking at other comments, it sounds like they may not be as common in certain people, but seeing that dental cavities are one of the most common diseases according to wikipedia...
