Boy that Dr. is good! He did the root canal, saved my existing crown and
sealed it all up in about an hour and a half. The cause of the need for
a root canal was an old filling (around thirty years) beneath the crown
that had decayed below the filling so bacteria got into the pulp chamber
and hence the root canals.

He used microscopic surgery techniques and progressive x-rays to make
sure he had managed to clean out the roots all the way to the very tip.
He used some sort of composite ceramic filler instead of the old standby
gutta percha. He etched the insides of the root canals with acid so the
ceramic would bond completely and also to kill any lingering
bacteria.The operation was just about painless until it came time to pay
for it. (Just kidding I can afford the best care for my teeth. I'm worth
it, after all.)

Total cost $1,985. Yikes. That would almost buy a new stainless steel
anchor for my Swan 68.
