Had root canal in upper molar 15 mths ago - now got pain up above tooth. Dentist prescribed 300mg clindomycin x 2 morning, and lunch and 150 mg at dinner for 5 days. How long does it take to work and what's with the dry mouth and horrible taste in my mouth ?
Having one canal redone mid February - will, I need more antibiotics before then - these are awful.
Thanks for any help
