What can help clear an infection after getting wisdom teeth pulled besides amoxicillin?

Clindamycin et al: Clindamycin and Keflex are some common antibiotics used for oral surgery. However, Keflex can have some cross-allergy if you are allergic to penicillin.

Infected post-op: Amoxicillin is a very common and inexpensive antibiotic for oral infections. The infection following wisdom teeth extractions usually involve the bony socket requiring a strong antibiotic to control. There are several other antibacterial medications, like Keflex or clindamycin, that can be switched to if the infection lingers. I would advise drinking more fluids to flush the body of toxins.

Postop Infection: Amoxicillin would be the first choice, unless you're allergic to penicillin. Other choices include Clindamycin or keflex. More importantly, have you contacted your oral surgeon or been back to see them? You should, if you haven't. A postoperative wound infection can potentially be serious, and could lead to an abscess requiring an incision and drainage procedure, or even osteomyelitis. See the doc.
