instruction: hi doctor I had my lower right side first molar extraction about a month ago my dentist prescribed a course of antibiotics the pain persisted after I finished the course of antibiotics and so the dentist again prescribed a five day antibiotic course a week went by with no pain and then the pain re occurred my medical doctor prescribed a third course of antibiotics now I fear that there is an infection under the gum line that is not being addressed by the antibiotics since I started the latest course of antibiotics the pain is on and off when I have the pain it bounces around even to the head I feel there may be some nerve damage when the tooth was pulled I am taking clindamycin for this issue also I am on insulin for type diabetes cyclobenzaprine levothyearoxine and lisinopril my regular dentist wants me to see an endodontist on the theory that one of the neighboring teeth is infected and their solution is to do a root canal I hear that the root canals are a bad idea as a dead tooth is left in place to seep bacteria into the body if possible can I get an antibiotic injection at the site of the infection please give me your thoughts thank you
