This question maybe more for a dentist but here goes; I had a tooth extracted two days ago, on Friday the 30th. Everything seemed to be progressing normally, some soreness around the extraction site, and where I was shot up with novacane. But after two days now I'm still pretty sore and at the extraction site it looks like a white puss sack developed. It's hanging down a little bit, I can feel it with my toung. Is this the blood clot or an infection starting? I thought that blood clots were red in color and not white?
