I had sensitivity to hot and cold a top back molar. When I went to the dentist they discovered the tooth was cracked. She drilled the tooth and prepared it for a temp crown. A couple day later that tooth was hurting and I had to take tylenol for the pain. I called the dentist before the permanent crown was supposed to be put on to inform them of my issues and they said it was normal and that once the permanent crown went on the pain should stop. Well it's been one week today since I had the permanent crown put on and I am still in pain. It is cold sensitive and it aches like a pulsating pain. I still have to take tylenol everyday to help it. Is this normal and will it eventually go away, or did my dentist miss something? They took x-rays before and after the crown.
