That would completely upend orthodontics too, if there was an option to regrow crooked teeth rather than yanking them into position with wires.
As for crooked teeth, it seems to me that Levin et. al. are unlocking the patterns that govern such things, and we can hopefully look forward to even jaws and even correcting deformed bone structures.
It's interesting to try to think about what form a machine would take for "re-imprinting" new skeletal structures into existing bones, eh?
the grinding/taste/vibration/experience of a filling is much worse for me than the experience of an extraction.
I don't know if that's rare or not -- but I have a very real aversion to the experience of dental grinding equipment, and that stuff tends not to get used much if at all during extractions.
I imagine some kind of gel that would react with the cavity to build some indestructible filling without any mecanical intervention.
