My temporary crown made me have a gap. I didn't have one before. Will my permanent porcelain crown have a gap between my teeth?

Temporary crowns are actually very difficult to make,and contact between the adjacent teeth is very important. Let your doctor know that you are trapping food in between these teeth and heir she should make you a better temporary crown.but why have temporaries? See a doctor who uses a cad cam device that makes a crown while you're in the office with no temporaries!  See Cerec and find a Cerec doctor near you.

I am sure that your dentist will make your permanent crown fit you teeth properly without a gap.  Let them know of your concern and they will take good care of you and give you a nice result.  Good luck!
