As someone who suffered with a root canal tooth for nine years, before finally having it extracted, I second magoo2's suggestion to avoid a root canal, if at all possible.
If I could have a "do over," rather than getting a root canal, I would have sought a biological dentist to get a second opinion. At the time, however, I'd never heard of biological dentistry. That was almost 20 years ago.
My botched root canal required five visits to two different dentists, because I kept experiencing pain, despite the dentist telling me that I "shouldn't" have pain. Eventually, I learned about
biological dentists, found one, and had my root canal tooth extracted. Ideally, though, we should try to keep all our body parts. I don't believe we have "spare" parts.
Check-out the following interactive meridian tooth chart:toothbody.com/learning-center/meridian-tooth-chart"Each tooth is related to an acupuncture meridian which is related to various organs, tissues and glands in the body on this particular meridian or "energy highway." This connection can often indicate your overall health and wellness by reviewing your dental condition. If a person has a weak internal organ, the condition of the associated meridian tooth could make it considerably more problematic."Incidentally, the above website is that of a biological dentist in St. Louis, MO.
