Would this not require us to only grow baby teeth?

Maybe if a person’s already had all their adult teeth removed, then you reactivate the gene instead of giving them dentures? Though, that means you might need all your teeth pulled if you lose some and want to regrow a new set. Perhaps you could get the gene applied in only a small area? Though, if a doctor fucks up they might start a new tooth regrowing right on a healthy tooth, and that might be bad. Also, what might this do to the regrower’s jaw bone, since adult teeth embed into the jaw bone?
