Can a sensitive Cracked tooth cause a sore throat and ear pain? I had a sore throat for about 4 weeks, and the doctor prescribed an antibiotic. The pain went away. I also went back to the dentist during the antibiotics because one of my tooth was hurting. Can these be linked? My sore throat has came back, and my tooth still throbs and is extremly sentive. He is going to be capping my tooth, but he didn't see any infection in the tooth. Again, do you think this is linked, or should I go to ent doctor. Thanks for your help.
