I have been having pain in the back of my mouth. It's located on the bottom of my mouth where my adult wisdom tooth should've grown in, but they're impacted and haven't been removed. I looked into my mouth and I can see redness in the area and a tiny hole in the center of my gums where the wisdom tooth would be. I have a yellowish bloody discharge coming from the hole. I also need to tell you the tooth right next to this issue is somewhat rotten. I had a cavity filled and it fell out twice so I haven't got it fixed in over 6 years. Can you please tell me what this is?
