Do I need to see a dentist? What might this be? Is it normal?I had two bottom wisdom teeth taken out about a month ago. I kept having to go back for dressings because of the pain. I moved and I was sore but eventually it went away and I was fine, however a few days ago I woke up and my gum next to the bottom right molar is swollen and if I push on it this gross smelling/tasting puss is coming out and my cheek is swollen. What could it be and do I need to go see a dentist and why?
