Your comment reminded me of a good friend who, against my strong advice, got 3 root canals done. She refused to read the book that I owned (Root Canal Cover-Up by George Meinig, DDS). Shortly after her root canal surgeries, I happened to move a long way away from her, and so we kept up with each other via email. She started having general fatigue, and I informed her that it might have been caused by the root canals harboring an infection, but she said she was pleased with her root canals (done in Thailand for a fraction of the cost it would've caused her here in New Zealand). I had no idea that she became seriously ill, as her emails did not mention that. A little over a year later, I received a shocking email from a mutual friend, who informed me that my friend had died of osteomyelitis, with her doctors clueless as to what was causing her bone infection.

I felt so frustrated and sad. Had I known that she had been diagnosed with osteomyelitis and was gravely ill, I would have begged her to let me pay for the removal of her root canals to show her that once the source of the bone infection had been removed, she could regain her health. I never had the chance.
