Re-grow teeth?

I was talking with a friend, who said that he heard about how the gene that controles tooth growth was found. And that tooth rejuvination, would be possable. I figured that if anyone could "debunk"or afferm this I could find them here.
Anyone hear anything?

Can I be first in the line to test them please?
I lost most of mine in a bike accident in 1975

I guess my friend was right.
You can "google" regrow teeth. Isn't sciense great?

Sorry I misspelled science. We all have our moments.
I will be very cool, to be able to go to the doctor and say "I need this", And be given a pill. And wow good as new.
I have been told that in twenty years we will be able to reproduce ANY ORGAN, includins eye's, and lungs.
"Will that be pick-up, or delivery"?

It'll probably cost alot just like all those other breaking scientific discoveries out there. If not, my grandpa will be the first to sign up! All his teeth are fake
