I'm 24 years old and in good health. I went to my regular dentist on 1/13/06 and xrays showed a large abscess in tooth #10, as well as a smaller abscess in tooth #20. On 1/17/06 I had a RCT done on tooth #10, as well as an incision in the roof of my mouth behind that tooth to help extract the infection. On 1/19/06, I had a RCT done on tooth #20, with one 0.05mm post placed. I have been on Antibiotics since 1/13/06, taking Penicillin VK 500mg QID, so I'm now on my Eighth day of antibiotics. I am sore, but not badly, and not bad enough to warrant pain meds, however, I am running a fever around 100, which was not present over the past few days. Is this a cause for concern, or is this par for the course with such an abscess?
