Dentist here. Sorry to be the bearer of bad news but regenerative dentistry is still some time away.

The linked article describes that they have discovered new pathways in the development cycle of teeth. (Akin to learning how something complex like your fingers develop from a fetal cell mass.)

This is a great start for sure and vital research.

But still some way before we are able to turn these developments into something actionable in a clinical setting.

What kind of time frame do you think we're looking at for 3d printed gum tissue? My understanding is that the issue is with the collagen matrix that bonds the tissue to the teeth.

It seems like that sort of material is very amenable to 3d printing.
