Hi, about three weeks ago i had fillings done on my teeth. Within a week of this procedure, I began experiencing persistent throbbing pain. Returned to my dentist and where it was confirmed that I had an infection. Was put on antibiotics for approximately 8 days. Everything was back to normal, until a two days ago leading up to last night, I experience the same kind of pain, was unable to sleep. I'm not sure if the pain is directly related to gum or my fillings as the pain radiates to other teeth and the gum line.
