I had a temporary crown on one of my molars, which hurts really bad. After two weeks, I went to the dentist to get the permanent crown on. I told him my tooth still hurts so he decided to put the permanent crown with a temporary cement. He said I might be needing a canal if the pain does not go away in the next few days. After a week,my tooth became fine. I went back to my dentist to have the temporary cement replaced with the permanent one. However,he could not take if off and he would damage the crown if he will try harder. He then decided to leave the crown with the temporary cement for now. Is this safe? How long does the temporary cement last?
All answers are greatly appreciated!
