I had 2 teeth extracted upper and lower jaw(13+19) 3 days ago. The lower extraction feels swollen... itchy and appears white in the socket along with blood substance, assume it's part of the clot. Upper extraction, hard to see but has some sore on the outside of the gum. I am on amoxicilln 500 but also had gastric bypass 5 years ago and don't think antibiotic is being absorbed appropriately. Is this white stuff, swelling normal?
