I am coming to understand my own tooth that I had a RC done on. It has been sensitive for the entire 8 years. If the origional infection really hasn't gone away, why don't the dentists tell you up front? None of what you said was ever told to me. I only know the proceedure cost a bit of money, and that my future with this tooth isn't so good. Is it all about money? I am dumbfounded that dentists are not up front with information, and this make me leary of my current dentist, when I don't care for them to begin with. I also was told I need a crown on a tooth. How do I know this is true? this will cost $900 and I am on medicare/medicaid, and would have to charge the proceedure. Now I am not so sure I actually need one. He did not say that there was further damage to the tooth, or that the filling was coming loose. My money situation is critical, and I hate to invest without knowing for sure that this is a necessary thing to do. I appreciate your responce, ginnie
