No, but, would you take the gold ones too?
Do they have the same mercury problem? If not, no need to. However, I'm an organ donor, and if I don't mind somebody having my corneas, heart, lungs, liver, etc., then I don't mind if someone takes my gold crowns, if there were some benefit to them. I'm just not that concerned about what happens to my body after I'm dead.
The Swedes weren't big on this, but the Germans did quite a bit of it back in the early 40s.
