Wow that is really scary as I was watching an on-line seminar this am and they were saying root canals harbor infections. You can’t feel the infection because the nerve is dead. They said they did research on 100 people who had their root canal tooth extracted and 100% of them were infected, with bacteria, even mold and fungus. Ugh I have had 2 if not 3. I’m super active too since my hip replacement in 2017. Started having pain in that upper leg area last Aug. Rested it for 3 months but pain still there. It’s just a mild pain but wasn’t there before I started playing pickleball. Have since stopped playing. Only walk and swim, climb stairs. But for the last dental work I had the doc said I didn’t need antibiotics any more. Scary. Getting an MRI this coming Weds. Wish me luck. Thanks you sooo much again for the info. I will definitely think of you next time I have dental work and ask for antibiotics.
