Can you share more information? Did it happen on it's own or was there some pharmacology used?

I've had cavities disappear, and teeth recover. I've had before and after x-rays side by side taken by shocked dentists. It's not to hard to believe, children teeth grow.

In all seriousness, if you have the patience and glasnost you should reach out to a scientist or related professional who can document this behaviour via bloods, x-rays, genomics or other means.

I study oral history and you’d be surprised what mundane information amazes people 50 years after the fact. Regrowing teeth would definitely fall into such a category, even if the evidence is unintelligible to present day dentists or you want aspects embargoed.

Like a shark, constantly changing?

A new set every ten to fifteen minutes. There are teeth all over my apartment.

That's cool. There is so much we still do not really understand.

Ever felt your hair growing on your back in full moon? /s
