Cipro for tooth infection

[mihijita]

I just had first root canal #14 through dental crown. Endodonist said there was pus -- infection. I have had allergic reaction to Levaquin and AzitheraI and have had side effects diarrhea and lightheaded from Cefdinir  and Cephalexin so he prescribed Cipro 500mg. Said he doesn't usually prescribe but given that it have taken Cipro 250mg in the past (or urinary tract infection with no side effects. Is Cipro as effective as other antibiotics for dental infection?

[Jerome Tsang, DDS]

Usually a course of clindamycin or Amoxillicin is prescribed for an oral infection but Cipro should work fine.

Thank you for responding to my question. It has been 12 days since I had root canal on #14. Took Cipro for 7 days. I'm still feeling lpain/discomfort on #14 and try not to chew on that side of mouth. How long does it for root canal to heal? Can and do root canal fail? What are symptoms of failed root canal. At the time of root canal Endodonist put temporary filled on crown. I have appoint with regular dentist for permanent filling in a week.
