The Clark books have about 50 pages of dental info. Hal Huggins wrote very good books, etc................
The metals are and will harm you for the rest your life, regardless if you pull it all now, but if you leave it, it can only become worse.
I suggest you read allot.
ALL ROOT CANALS are not options.
All metal crowns can be replaced with porcilian as a better option at about $1,500 each..
Mercury can be removed.
Many people have $10,000+ dental work and all work they choose as better options, also have their problems. I therefor suggest reading Hulda Clark's advanced cancer book for starters adn what she suggest for the dental is pretty much your options, unless your wealthjy enough to opt for laser and even then, dead teeth are forever dead.
Like Clark and you suggest, most choose death over loosing their false teethe, because those crowns are false teeth.
