If I were your treating dentist, I would look
for other potential source of
infection. In the mean time, if
augmentin and clindamycin are not effective, I would try erythromycin family drug, such as azithromycin or clarithromycin , paired with metronidazole(flagyl). If itis possible, antibiotic sensitivity test can be done in the lab to determine which antibiotic is most effective for the cultured bacteria. Hope this helps.
