Hi , I had infection in one of my molars, which was treated by RC method twice in the last 8-9 years. Because of this infection, I have developed swelling and pain in my lower cheek, jaw line and a part of chin. I gave up, and got this tooth extracted. However, inspite of 3 days of antibiotic dosage, the swelling and pain in cheeks area is not going away.. Do I need some kind of procedure to drain the pus which probably has accumulated in this area and causing pain and swelling?
