I had decades worth of crud drilled out of my jaw in the summer and autumn 
because of wisdom tooth extractions in which the dentist left parts of the 
periodontal ligament in the jaw. The cavitations are slow, and erode the bone 
over time, without pain. So the person doesn't know they're there, usually, 
until surgery is needed.

  **** Hi His!  Good grief.  What in the world did your dentist do to you?  I 
had a root canal more than 35 years ago.  It has given me no trouble.  What 
remains of that tooth supports a crown, which looks pretty nice -- although the 
original crown has been replaced once.  If you have a root canal removed, then 
you lose the usefulness of that tooth altogether, don't you?  MA (who probably 
has a couple more root canals in her future, as thirty-year old silver fillings 
are beginning to fail and the dentist won't replace them with composite)  :-(
