An astonishing story about Lithuanian Regina Prudnikova I just found on the USHMM "Some were neighbours" website:
United States Holocaust Memorial Museum : Some Were Neighbors
Part of the interview transcript:
INTERVIEWER: Well, but the Jews—they must have had all kind of golden rings.
PRUDNIKOVA: Well yeah, they did have. They probably were searched at the spot because they were forced to undress until they were naked there, you see. Some of them, the richer ones, were undressed naked and their teeth were extracted too. Even I bought one tooth, because I needed an implant.
INTERVIEWER: You bought a tooth?
PRUDNIKOVA: Yeah. Yes.
INTERVIEWER: Oh, so one could buy a tooth?
PRUDNIKOVA: Yes, a gold one. I don’t know how much I paid, but not much. When the Russians came, I bought the tooth form a woman named Mrs. Didžiūnas.
INTERVIEWER: And where is that tooth now?
PRUDNIKOVA: Here. [Points to a gold tooth in her mouth]
