I have 2 root canals on the lower molars. Had them both done within the last 5 years.

Do you recommend that they are removed for long term health benefits? Any safe options to have a 'tooth' there?

I know for a fact in the last couple of weeks one of them has some sort of crack in there, as I can get a horrid taste leaking from one of them.

I have never trusted my dentist fully either - maybe because I associate pain with him.
