I had a tooth extracted due to a bad infection. i was put on 300 mg of clindamycin. after 6 days, my face is still swollen but i have no pain. what should i do?

Tooth swelling: You need to tell your dentist and get checked to see if an abscess has formed where the tooth was.

Call dentist: Call the dentist who extracted the tooth and explain you still have swelling. You might need a different antibiotic.

See DDS ASAP : If tooth extraction plus the use of antibiotics have not diminished your swelling/infection, you must see the dentist/oral surgeon who took out the tooth for the to evaluate and possibly perform other necessary treatment, such as an incise and drainage procedure. 6 days is a long time for you to wait for resolution.
