Thank you for your question and welcome to Just Answer.
Levaquin is an antibiotic specific for infections in the lungs and urinary tract. See:
This is not an antibiotic that would help clear up a dental abscess as the bacteria that typically infect teeth and gums are different than the bacteria that infect lungs and urinary tracts.
FYI, no antibiotic will completely clear up your dental abscess prior to having the root canal completed. It will merely reduce the infection to a level that will enable the dentist to successfully anesthetize you for the procedure. Only when the root canal is completed will the infection completely go away.
Clindamycin is usually a good antibiotic for dental abscesses. It might take up to 48 hours for any antibiotic to start taking effect so take that into consideration. You might have a super infection, that is an infection that is resistant to antibiotics. In this situation we usually prescribe Flagyl at the same time as clindamycin (two antibiotics at the same time) to knock these infections down.
I hope this answers your question. If you would like to discuss this further or have any additional questions, please reply to my answer and I will get right back to you.

You are most welcome. FYI, Cipro is another antibiotic specific for urinary tract infections and would not help much with your dental abscess. The Pen VK is a good one for dental problems, however.
