If you were directing your last post to me, I had the cavitat done to determine if the jaw bone beneath the teeth had blood circulating through. If not, that's an indication of infection. I was trying to pinpoint problem teeth that could be the reason for my sinus infections.
As it turns out the problem area where I had the cavitation done was where a root canal had previously been removed without the socket being cleaned out properly years earlier.
Then I decided to get all the RC's removed and the Amalgam murcury fillings removed.
BTW, I still have enough teeth to get by, but I could use a couple more. My situation requires a partial that would require metal which I don't want, so I have been putting it off.
