Sore bottom teeth

Is it normal for a bottom tooth, directly below the upper temporary crown, to be sore 3-4 days after the temporary crown was placed.  I can't tell if this is normal or whether there is an issue with the lower tooth that needs to be addressed.  FYI - the lower tooth has a filling.  There is no pain with the upper teeth, the pain now seems to be emanating with the lower tooth now.  Thanks.

The bottom tooth may be sore if the temporary crown is too tall (bite is putting too much pressure on the bottom tooth) resulting in some sensitivity and discomfort.  Go back to the dentist and get it adjusted.
