There is nothing good about a root canal-its like smoking!
I read a small study in a book "Rescued by my Dentist" they measure 15-18 patients immune systmen then removed the metal in their mouth ( fillings-crowns root canals) and measured their immune system. On average it doubled!
This also would help many kinds of healing. Which would explain all the stories of people getting better from different aliments
Granted it was a small study-I think 15-18 patients. I would never get a root canal and I would pull any in my mouth
