I had 5 teeth worked on in the upper right side of my mouth. 3 days later one of the filled teeth became infected. The right side of my face was swollen and very painful to touch. My lip was also very painful to touch. I went back to the dentist, he said that he must perform a root canal on this infected tooth NOW. When the tooth was drilled, the dentist said that pus came out. He had me squeez my cheek to get more pus out. Afterward, the pain slowly subsided but it has been 2 months now and I still can't touch my face on the right side near my right eye with out a sharp pain occuring in my right cheek, just above the eye tooth. This sensitivity seems to get worse at night before I go to bed and ofcourse, keeps me awake part of the night. What could be wrong and will this ever get better?
