What is the least amount of time you can take amoxicillin  for a tooth infection and still be sure the infection is gone? After two days of taking the medication he will have a root canal, would three more days after the root canal be adequate?  My husband has just gotten over a very severe case of C Diff. after taking clindamycin for a tooth infection six and a half months ago.  It has been only three and a half months since recovery and now must go on amoxicillin 500mg Q12hours,( he also has 4th stage kidney disease thus this specific dosage), for a new tooth infection.  We want to take every precaution that safely addresses clearing up the infection and also all we can do to prevent another C Diff. occurrence!!  Thank You!
Hello, Its better to administer amoxicillin initially, prior to root canal treatment. This will help to relieve the underlying infection. I would suggest you to take complete course of antibiotics during the initial stages of tooth infection. Depending on the severity of infection, dose as well as duration of action of antibiotics may vary. Please do visit a dentist and get an opinion regarding this. Hope this helps.
