My dentist has finally got onboard with the science that root canals are all doomed, even if done correctly they leave dead tissue and are a magnet for infection. It’s highly shunned and called conspiracy nonsense by the mainstream but the recent science backs up that root canals are largely just bad. I’ve had a bunch myself, like 6 or so. I’m going for a car scan (3D cone scan) myself to see if there’s any infection in my bone or at any root canal teeth. I’m expecting to find that there is. Definitely worth going down the holistic look at this and how root canal’s are all doomed. I’m going to be getting implants over the next year or two, replacing all my root banks teeth and removing the dead tissue. it’s finally coming to light how these dead teeth left in place with root canal’s even done perfectly , leads to infections and bone issues over long term.
