an eye for an eye, a tooth for a tooth..

Here's a case of a "tooth for an eye":

Very interesting article... I guess I don't understand what the tooth was actually for though. I understand the bit about a plastic replacement being rejected.. but what is the tooth actually used for?

The tooth was to provide a natural body part that was unlikely to be rejected. Of course they could have used a good well machined piece of PMMA which if fully cured has never been rejected. Except of course when the surgeon used a sphere implant and tied four muscles on top of it. (Muscles sliped behind implant and forced it out, but one has to blame the material, not the surgeon.)
