A few months ago, I went to the dentist to have my premolar checked. It was so sensitive to cold. The dentist found out I have a pretty bad cavity on this tooth. He put a filling on it. After a month, part of the filled tooth chipped off. The dentist said I will be needing a crown. He put on a temporary crown two weeks ago. Last week, I went back to him due to some discomfort. I could not bite on the tooth. He then reshaped the crown but this did not solve the problem. I still cannot bite on the tooth and it hurts when I knock on it. If the pain does not disappear, the dentist said he will the permanent crown with a temporary cement as I might need a canal. I think the nerve is damaged. What should I do? What is the risk if the nerve is not fine?
I appreciate all your answers!
