When I had my amalgam fillings removed (all 20), the dentist found that all 4 of my bottom molars had thin, hairline cracks on each side of the tooth. My dentist said that these small cracks were caused by the mercury fillings.

You mentioned in your post that mercury amalgam "creates fracture lines in molars and causes the teeth to crumble later in life." Well, I would agree based on my personal experience.

It's also interesting to note that all my life I had nightmares (maybe 2-3 times a year or more) in which all my teeth begin to crumble and fall out of my mouth. I would wake up all frantic and have to feel my teeth to make sure everything was okay. It may sound funny, but it was quite a horrible nightmare. Anyway, I had all my amalgams taken out 4 years ago and I don't think I've had the nightmare since... it's been such a long time since I had the nightmare that I can't remember the last time.
