A failed root canal left infected root in the tooth, which caused a major infection, an abscess
, a need for another root canal on a nearby tooth
, and eventually the extraction of both teeth. I have had a fever for 6 months, since the onset of this infection. I have no other underlying illnesses, no health problems, no inflammatory illness. Prior to this I was healthy. I don't drink or smoke. The only other thing that's popped up during all this is I have a small cyst on each side of my thyroid.
