Many months ago, I had some words with my dentist, and it ended with me doing the work myself. I suspected a "void" under a filling. The molar had a recent root canal, but there was still some irritation. So I drilled out the filling {I have special equipement for this} and discovered I was right. So I cleaned the decay, disinfected the area, and filled it {with the appropriate materials} and sculpted and cast an acylic crown. All standard procedure. Now, according to the x-ray, there was an infection "around" one of the roots. I disagreed that it was caused by bacteria, and decided against a surgical procedure to correct it {not 100% success rate}.
Since my own work,{many moths ago} things were fine, until a few weeks ago when the tooth started to flare up a bit. I dismissed it as typical tissue re-growth. BUT, sunday night pain was so bad, I thought I would have to go to the emerg. So I removed the filling {very painful} and proceded to drill into the tooth pulp. Well....I got a bleeder, about a mouth full. Now the funny thing is, there should have been plasma and a really bad taste if it was an infection. This is where I find things don't add up. It may have been an infection, but I doubt it was bacteria.[ I was too freaked out to gather specimen samples of blood].
After I fixed-up the tooth, the pain was gone, and now it feels almost normal again.[I am also taking Antibiotics in small doses for safty]

Now here is what I think happened. The parasites have oocysts which can circulate, and the yeast have spores. But they cannot survive just anywhere. I believe, one or the other found this little haven in a dead tooth. They start to produce prostaglandins, and this results in an inflammatory reaction. The mast-cells start over- producing histimines, and this causes pressure to build under the tooth. When I released the area of blood, I drained out the cells, and granules. This restored things to normal. Now, the other day, I was stung by a wasp. The area of the bite swelled up, and has been a problem since. So I took a sample of the bite area, and examined it. I found an abundance of very active t-cells, and mast cells. The histamines were being produced at a very active rate. [this accounts for itch and swelling]There were also b-cells present, and everyone is doing their job. But guess what I found? Small {I think yeast} cells in the area. Could this be causing interference in the normal healing process? I don't know, but I think it is causing more than normal over-reaction from the immune-response system.
Alright, thats all I have to say for now.......... Shroom
