Earlier quoted context omitted.
All a dentist would do would be to wipe off any large debris (as long as noxious chemicals aren't involved, you don't really even want to wash it) and then stick it back in the socket. Maybe pack some cotton rolls around it to keep it in one spot for the first 12 hours or so. Doing this on-scene ASAP is strictly better than waiting until you get to a dentist.
Would it still take root if it was placed in backwards? If it was someone else's tooth? a particularly well shaped rock?
