My experience is that there is no way to disinfect a root canal and make it a viable part of the human body. I believe Hal Huggins who has dedicated his life to research on this. Here is some of what he has to say:
"Root canals are a zillion times worse than mercury fillings."
"I see people pushing along in a wheelchair. I wonder when did you have your root canal done? Because root canals so far have turned out to be one of the most vile things that I have ever run into...." ~Dr. Hal Huggins, D.D.S., M.S.
I recently wrote to him:
Hal,
I am getting people saying Epiphany with Resilon is good to put in root canals and it seals all the roots. can you please address this? do you have any write-ups on this product?
His response:
"Write-ups will be in the form of one giant expose! They are looking at the wrong tree to “bark up.” The problem is the infected periodontal ligament on the OUTSIDE of the tooth. Sealing the pulp chamber does not effect the dentinal tubules adjacent to the periodontal ligament- nor the infected ligament itself."
