I have a dentist (in my opinion screwed up a root canal on a wisdom tooth, which he filled first, put a cap on - then five days later decided to do a root canal. After the canal was done, my cheek swelled up and has remained grossly swollen for five days now). Instead of prescribing this when I first complained of painful swelling, he has now ordered two antibiotics, metronisazole 250 3 x a day AND azithromycin 250 for 5 days concurrently. Even my pharmacist thought this was VERY unusual...what do you think?
