I have just had a root canal on right upper molar tooth. I had a crown, so the root canal was done through the crown. I had it done 2 weeks ago. I was still having pain, and when I went back for the hole to be filled, the dentist decided to remove more of the nerve. I am still in terrible pain. When I eat hot or cold foods or drink hot or cold liquids I am in agony on the whole right side of my face. The whole side of my mouth lower and upper teeth are throbing. I have pain up into my ear. I went to the ear doctor, and there is nothing wrong with my ears. I am taking Motrin. The dentist said she will do a root canal on the next tooth if the pain continues. I am worried that I will have unneccessary root canals done. Do I have an infection? I really need help as I am living in Berlin, Germany. I will be returning to the States in June.
