hi my boyfriend went to the dentist because his two bottom teeth were bothering him. when he went he told the dentist that he thought he had an infection before they did anything the doctor said he didn't see any swelling but everyone else did. he went ahead and drilled the two teeth and filled them, now his lower lip still goes numb from time to time and his mouth sometimes feels like it on fire along with constant pain. It has been nearly three days since his visit to the dentist. The same night as his visit at the dentist, we went to the hospital because of the symptoms, and they prescribed him ibuprofen, vicodin, and penicillin. None of the meds seem to be working. Can anyone tell me what might be going on?
