David, I think those fillings are dental amalgam, not lead. Maybe they contain lead, but it was my understanding that some concern exists because they contain a small amount of mercury. But I've got a bunch of them too, have a couple decades on you, and am not worried about them--as long as I keep my teeth!
JDW, the bald eagle deal was indeed specifically related to carrion-eating. Remember, that was in the days before the lead restrictions, so if you shot a duck, pheasant, whatever, crippled or dead but not recovered, an eagle might end up eating it and ingesting lead. Some apparently did. Today, any raptor capable of catching a duck wouldn't ingest any lead, because a) we don't shoot them with lead any more; and b) if they already have shot in them, then it'd be the carrion eaters that would be ingesting the shot (whether steel or other nontox in the case of a duck, maybe lead in the case of a pheasant), not the raptors taking healthy birds on the wing.
