I had a wisdom tooth extraction 6 days ago and i am still in a lot of pain, the wound looks like it has 4 round corners closing in with a small gap in the middle with a shape of a plus sign, I keep my mouth very clean, I brush twice a day, use mouth was 3 times a day, and floss, avoiding the area of extraction. I did some research on the post extraction symptoms, and I saw that people's pain only lasted 2-3days, I was wondering if it was something I should worry about?
