Remaking/fixing a root canal

Hi,Does somebody has experience or knowledge about a root canal treatment with just endocal, the Canadian alternative dental product (and without the gutta percha from personal natural process preferences)? and experienced new or more problems, such as in the throat, muscles, phlegm and skin face after the treatment? (some problems had worsen after and I also have the dental "structure" suppose to be also more natural on it) and What is your experience/knowledge in that cases with remaking/trying to fix the root canal, a regular one, with assumption that something can be not proper/accurate there and can the dentist remove just the material that had being put inside/the root canal treatment without the whole tooth and try to do a deep filling instead if it's possible?
I'm aware about the root canal dangers and the extraction possibility but made a decision to give it a chance, first for the more alternative treatment. Tweet
