Well, that is a pretty generalized question, but since you feel qualified to diagnose dental problems without seeing a patient, proper examination, x-rays, or well heck proper schooling or a license for that matter, why shouldn't I? Assuming your story is true, and I have no reason to believe otherwise with all the wonderful truths you have been exposing these bloggers with, I'm going to bet there is more to the story. Maybe the teeth had new abscesses. Maybe it was power of suggestion on your part, who knows. I'm not a big fan of Amalgam myself, but I'm not fearful of it either.
