> With good hygiene and dental checkups twice a year, you can reasonably expect to avoid cavities altogether. Your comment is self-contradicting. The only thing that dental checkups do is allow cavities to be flagged before they progress very far. Also, I feel that in this context "good hygiene" is a weasel word, in the sense that implies that any occurrence of a cavity can only be explained by the absence of good hygiene. There are many factors to cavities that aren't addressed by hygiene, such as vulnerable teeth and cavity types such as root cavities, whose primary risk factor is decreased salivary flow.
