Bryanna...I have read your posts on root canals. I see merit. It seems to me that it is possible that they entrap infections. I accept that there could be an issue ...hence "controversial." And in some cases, maybe they are not a good idea. I've also read Dr. mercola's opinion's on the topic. I spoke to a well known and respected oral surgeon in my area who performs implant "surgery" ???? And he felt that they (root canals) might be appropriate in some cases (did not elaborate), but probably the better route in many, if not most cases, would be implants. (But when a graph was done on me, my pain and health worsened). So, for now, that (for the most part) makes sense to me. I think they might be ok for some instances. I do know people who are up in age, who have had many root canals without any issues. At the moment, and likely indefinitely, I would double or triple check any procedure a dentist suggested to me and listen to my instincts as well.
