I Recently Broke My Tooth. My Dentist Put A Temporary

i recently broke my tooth. my dentist put a temporary crown in my mouth for two weeks. I then went back for the permanent crown and two days later started feeling a numbness in my cheek and a blister on the roof of my mouth. I went back to the dentist and everything looked fine and I didn't have any pain at all around the tooth. Dentist removed crown concerned I was having an allergic reaction. She put the temporary crown back in. My symptoms improved in a few days. It's been a week and now I'm nervous to have the permanent crown put back in. I have 4 other crowns that are a few years old. The dentist said she used the same cement as in the past. Could I be allergic to the cement? I have had other allergic reactions to medicines before.
