I had a upper molar extraction 3 weeks ago, now I am having pain in the region and when I touch the extracted teeth area I can feel some small swelling and slight white inside gum. Some of them feels like needle on touch. Pain also in the area where these weird things are. Gum also slight red at that area than rest of the other area. It causes pain mostly when I eat food or I do activities with mouth like talk. At night or morning there is no pain.
