Before they can put in an artificial tooth, they have to lay the groundwork with bone graft material. What is bone graft material, you ask? Well, I had the following conversation with the dentist.
"What is it made out of?"
"From dead people?"
"But they clean it."
I guess it's no different from getting an organ transplant, but there's something strange about having a crushed-up dead person inside your mouth.
What if the bones came from a murderer? (Or a bone thug?)
Still, as Kelly noted, the Berkeleyan in me should applaud this: At least it's organic.
