> I’m 52 and have never had a cavity What? Certainly that can't be true.

  There's a big genetic component to oral health, such as the DEFB1 gene. Some people are lucky and never get cavities. Others are unlucky and need constant fillings despite a stringent oral health regimen.

    I imagined as much. I'm 35 and had a few cavities, and have friends who've had loads of cavities and even teeth removed. But no cavities at 52, I never thought that effect was so extreme. I would like to understand what exactly in your genes is preventing cavities. Because from what I know cavities are largely bacteria attacking your teeth? So some people have better defense afainst those bacteria? How exactly does that work? I mean, microscopically.
