Hi there...I had a 3 surface composite filling placed on #3
approximately 3 months ago.  It was very sensitive to cold immediately
following for approximately 2 months.  Then all of a sudden it started
becoming sensitive to hot, to the point I could not drink my tea in the
morning.  Then the tooth became sensitive to pressure over the course
of a couple days.  I called my dentist and went in for an exam.  She
tapped on the tooth and found an area on the lingual that was very
sensitive.  She took a look and asked what was going on at home/work
and said that it appeared I had a high spot on the filling, I was
clenching/grinding at night, and she filed the high spot down.  The
next day I was in even worse pain to the point that I must have sipped
200 oz. of ice water throughout the day.  I called her office and she
could not see me (Friday)for an emergency and prescribed an antibiotic
and vicodin.  I took 1/2 of a vicodin pill when I picked up the
prescription and then another 1/2 on Saturday.  It is now Monday and
the tooth only has mild sensitivity to pressure.  It is fine with both
hot and cold.  She has me scheduled for a root canal on Friday, but I'm
not sure now.  She is out of town until Wednesday and I will call, but
wanted to get other professional opinions based on a description vs.
observation.  Thanks for your help in advance.
