Wisdom Tooth (Hardened Puss)

St
Hey all! I have a concern and I don't know if I'm in the right place to ask about this. For the third time I've taken out a hardened solid piece of puss from the inside of the pocket of my wisdom tooth. I sometimes use a sanitized toothpick to make sure there aren't any food remains in there. But this time I felt a little bit of pressure so I went to go check it out. The more I maneuvered the tooth pick in the pocket hole the more I saw something was coming out. Freaking disgusting but can anyone tell me more about it or what to do? If the same thing has happened to anyone? I've been to the dentist already and they've told me my teeth are fine and that they're just coming out. So far no infection and they have space in my mouth and they're coming out straight but both bottom wisdom teeth are impacted with a pocket over it. Here's a photo of it. It's disgusting to beware...
