I was hoping that my weekly dental appointments would come to an end,
but no such luck. Here's what happened:
RCT on #19, dentist did a crown buildup, and while working in that
area recommended replacing a small amalgam filling in #20 (distal)
with composite. Things are fine for one week. Then while chewing I
notice a sharp edge on #20 and two small white slivers barely hanging
on. Other than the sharp edge no discomfort. About a week later I
notice some pain while biting down. A very small area where the
filling was placed is sensitive to biting force pressure (_not_
release). Dentist inspects tooth and concludes that the filling has
chipped and reschedules me for replacement a week later. This
replacement was done yesterday. Now there is no pain when chewing.
However, I can still find a spot where the release of pressure causes
discomfort.

Any ideas what's going on here? The tooth was completely asymptomatic,
then chips, then sensitive to pressure, and now sensitive to release
of pressure ?

Thank you,
