I can't see how genetic modification would be the correct way to treat such injuries. Maybe substances that can trigger epigenetic effects would be more relevant to such things. I understand a Japanese team is working on a means of triggering tooth regrowth by means of an injection. I've got no problem with that. Or something like Skele-Gro from Harry Potter either.
