Yikes... that's rough. I know the dilemma of having to decide what the heck to do with your teeth. I had a root canal extracted on the biggest molar in my mouth -#14. I'm missing a tooth there because I can't decide if I want to fix the gaping hole by getting a bridge - which would destroy the 2 adjacent teeth - or an implant, which would drill into the cavitation. I couldn't decide what to do so decided to leave well enough alone and do nothing for the moment. It's the pits having a missing tooth but I've gotten used to it. When I read about the crap/toxins/bacteria that root canals bring I couldn't get it out fast enough. I know HC recommends getting teeth removed when you're ill. I'd personally like to keep as many of my teeth as possible because I think that having teeth/roots in your jaw maintain the integrity of the jawbone,cranium etc... But, I'm sure you'll make a wise decision whatever you choose.
If money is a concer you can try to find a Dentist that offers Care Credit. It's basically a loan but with very low % - maybe 1.9? That's how I paid for mine.
