Some people have a natural ability to repair teeth - I'm one of them. I've never had a dentist find a cavity in my mouth, though I've had perhaps a half-dozen cavities over the years. (I'm in my 50s.) When that happens, I just get double up on brushing (I usually just do two quick brushings a day), and the cavities heal over within a week or so. I realize I'm fortunate, but my teeth do heal cavities on the rare occasions I get them. I haven't been to a dentist in over 35 years (my Mom paid for the last visit!), and with the exception of the inside of my bottom front teeth (where a small amount plaque flakes off every couple of months), I have no significant plaque buildup or discoloration. So, long story short, this is definitely possible, and should be inducible in others once we understand the mechanism.
