I had an abcess on my gum twice in the last 3 months. The tooth had 2 root canals done and finally was extracted. Before the extraction, I had been on Amoxycillan 750mg for 6 days. When the extraction was done the dentist said if was still very infected under the tooth. It was almost as if I had not been on any antibiotics. He scraped the area and did not stitch it so the infection could drain. After 3 days my cheek and gum started swelling again but I was not having pain. I went back to the dentist and he started me on penicillan 500 mg 4 times a day for 7 days. I have completed 4 days of this and the swelling seems to have gone down quite a bit, but I can still feel some throbbing occasionally in the empty cavity. The cavity seems to be healing. Can there be something else going on? Or if this does not do the trick, what might be the next course of treatment?
