Can I call you "Chatty" for short?

Actually, I asked the endo if the decay came from the missed canal and he
told me that it hadn't.  Part of the canal that my dentist missed had
calcified and the endo is still trying to find it.  So, it appears that he
just didn't clean out decay that was in there.  My understanding of a root
canal was that the dentist would clean up the tooth and fill the canals.  I
assumed, maybe wrongly, that this would entail getting rid of any decay in
the tooth.  The dentist obviously didn't do a very good job of "cleaning up"
the tooth.  It's a pretty big tooth so I don't think the reason that he
didn't clean the decay out was to leave enough tooth to hold a rubber dam.
All I know is that he left me sitting in the chair to call my dentist and
tell him what the problem was and the dentist said he would pay for the endo.
The endo took the decay out and is in the process of redoing the root canal.
He even took the tooth down so that there was no chance of my biting down on
it and causing more problems so I am pretty sure that was ample tooth there
to begin with.

Like I said it my other posts, I had two teeth side-by-side done at the same
time.  All of syptoms went away after he took the infection out of my molar,
but some are beginning to come back.  I am now wondering if maybe the dentist
left decay in the other tooth as well.  I go back to the endo on the 9th so I
will have to ask him.  Symptoms aren't quite as drastic and the tooth is much
smaller so maybe there's not as much infection in that one.
