You do have to have sealant re-applied periodically.

  It can depend, though of course genetics are probably a factor. I had sealant applied when I was a teenager, but never since. I'm now 38; still - at least, as of my last dentist visit a couple of months ago - no fillings.

    It's not genetics. It's all diet and hygiene.
