I’ve been dreaming about this for forty years - ever since I read about some guy that got irradiated by a UFO and a couple months later his teeth started falling out and they found a brand new set growing in beneath them. Wouldn’t it be nice? I think they have made some advances towards this in the UK also though it’s targeted at accident victims needing major facial reconstruction. It would also be interesting to see how long elephants might live if we could regrow their teeth - disease and predators aside that seems to be the limiting factor to their life span at the moment.
