I had to deal with something similar last year (or the year before -
can't remember at the moment). I couldn't find a whole lot of
trustworthy-looking information (but here are the url's I found, for
whatever they're worth).

I called dentists and oral surgeons across the United States and
asked for their opinions on some of the problems I read about.

What I finally decided to do was have my tooth extracted (that's the
fancy word for "pulled out"). My tooth was way in the back, and I
was told it was just not a critical tooth. And from what I could
gather, the possible dangers of root canals were worrisome enough to
not want to go that way.

Here are the sites: (and I'm sure there are newer better ones now
than these)...
