question: I have been on Ceftin 250mg bid x 10 days for an infected tooth- i had a root canal yesterday and now i am running a low grade fever 100.0 after taking ibuprofen 600mg po.  My dentist told me that I had a lot of infection in my tooth and a lot of drainage.  I am still having a lot of pain in my tooth but my dentist told me that this can happen after RCT.  Should I be worried about my fever?
