question: I recently got all four wisdom teeth pulled back in December. Yesterday I decided to eat popcorn and thought that a kernel may have gotten stuck so i tried flossing, brushing, using a oral pick, etc to try and get the \"kernel\" out, but nothing ever came out. I noticed that I still had some swelling and that my mouth was very tender. The swelling kept getting worse so i decided to rinse my mouth out again and noticed a black spot where my stitches were so I poked at it with a oral pick. Once i did this pus started to gush out from the spot. What does this mean, and why did this happen?
