IDK what posts you were reading but almost all endodontists, after they scrape out your pulp chamber and tubules, fill them in with gutta percha, which is not amalgam.
When they do an apicoectomy and they clean out the infected root tip, they're supposed to fill it in with a biocompatible material. Your dentist thinks silver-mercury amalgam is biocompatible?
Dentists by law are required to keep records. You need to go back there, slap him in the face, grab him by the lapels and say, "LISTEN YOU MONSTER!!! WHAT F*CKING PROCEDURE DID YOU DO ON MY TOOTH?????"
Although the Mercury issue is important, as well as chelation I can tell you from experience that root canals with or without the mercury can cause you a host of medical problems.
I first became aware of this while reading a book provided by a holistic dentist in his waiting room waiting my turn to get my teeth cleaned. I had been having 4 or 5 Sinus infections a year that allopathic medicine treated with antibiotics, along with Fibromyalgia in my right shoulder, and arthritis in my right hip that was so bad I could walk more than 2 or three blocks. There were other medical problems, but I think they were brought on by the multiple antibiotic sessions given me 4 or 5 times a year.
Even after reading that my teeth might be the problem I didn't do anything about it for a few years because my teeth wern't bothering me. Finally I decided to get all the mercury removed as well as the root canals.
All my health problems were eliminated all most immediately except for the digestive havoc the antibiotics created. My advice, don't get any root canals, and remove any you have.
Anyway go to this sight and scroll down about half way until you find the Thomas E. Levy video re: root canals.

So are gold fillings 100% gold-i assume probably not . Are they usually mixed with some other type of metals? My grandma had gold fillings.
I have a few root canals and they seem to flare up every now and then-teeth are a pain in the #$#$$.
