Up until a week ago, while I have a somewhat sensitive mouth, I have not had severe pain. When I went to the dentist, I found out I had a couple of cavities. When I had them filled, on the left side it only numbed in the front for some reason. The dentist didn't know why.
Since then, I have had severe pain in my nerves where I had the cavities filled. It has gotten so that I can't have anything even a little cold. The pain radiates into my head, giving me a severe headache.
Did the dentist do something wrong? All of the explainations I can find for toothaches like this would mean that I had pain before. I can't find a reason for why I would have paing only after I went to the dentist. I have had cavities filled before and have never had this problem.
