I personally thank fluoridated tap water for my never having had a cavity ever because I have no idea how I have managed otherwise.
I've had a few things that looked like cavities starting, then died. It may have never been a cavity in the first place, as every dentist I've seen has commented on it, only for me to explain it's over a decade or two old with no change.
