Pain from temorary crown

I had a tooth shaped for a permanent crown two weeks ago.  The dentist inserted a temporary crown while the permanent is being made.  Since the temp was put in, I've had pretty consistent pain and moderate (to severe) sensitivity to cold.  Advil will get rid of it, but only for 6 hours or so.  The temp seems to fit properly.  My bite doesn't seem off and it doesn't hurt when I bite down.  I went and saw the dentist to discuss the pain, and he said it looked okay and that he'd like for me to bear it until the permanent is in.  He said it was typical that temporary crowns can sometimes cause pain.  He said he didn't think I needed a root canal, but said it may be a possibility.

My question is, is this normal and should I have the permanent crown "permanently" cemented if there is a chance I may need an additional procedure?

Sometimes people experience discomfort from a temporary crown for a variety reasons including some pulpal inflammation or irritation due to the drilling, poor fitting temporary crowns, etc.  

You can have the permanent crown cemented permanently but you can also discuss with your dentist the possibility of replacing the temporary crown to see if it may be a bad fit or some other underlying problem.  You can also temporarily cement the permanent crown with a temporary cement but sometimes it is hard to get off and can crack or break when trying to remove it which may start the process over again.  Your dentist or you may not want that though but its an option.
