Root canals are havens for bacteria growth which can disrupt immune system function and produce health problems in other parts of the body. I had a root canal about 15 years ago and steadily my blood pressure was rising through the years. Doctors couldn't figure out why. Got the tooth pulled after watching the vid and within a month it came down to normal and I feel a ton better.
Once a tooth is dead, get it out of your mouth.
The more I see the white hat moves here, the more I see a massive smokescreen. Whatever happens, it's going to be nuclear.
