I got a root canal done, and my face was swollen 2 days after, taking antibiotics and vicodin, its now been 5 days and still have swelling. help?

See a Dentist Again: The aim of root canal therapy is to eliminate an infection within (sometimes around) a tooth. This usually works quite quickly and well. However, if the infection doesn't clear-up, especially with the support of antibiotics, you must go back to the dentist. Perhaps an additional antibiotic is needed. Maybe more treatment has to be done. Facial infections are serious and dangerous. Go back again.

Contact your dentist: It was not clear if your root canal treatment was started or completed and how much of the original swelling is still present. It is possible you may need some additional treatment and/or a different antibiotic. You should contact your dentist for re-evaluation.

5 days?: If swelling is coming down it is a good sign. But if it remains the same it is not a good sign. Visit your dentist.

Return to DDS: Swelling needs a path to drain. Clearly from your question this is not occurring. I suggest you return to your dds to be reevaluated. Sometimes the type of antibiotic may need to be changed too.
