Going to see doctor to check the lymph node. The swelling stays same, 1-2 cm.\n\nSorry about this weird question.\n\nIn Feb, I removed my lower impacted left wisdom tooth. When I tried to take care of the socket after surgery,\nI was not very careful. Some oatmeal grains stuck into the hole.\nI tried to rinse with water, used tweezer to pick up the grains, but I was not sure if it was all cleaned.\nI felt some stuck deeper inside and could not pick up anymore.\n\nAfter few months, the gum closed and now it looks like there was no tooth before.\n\nIs it possible that the hole can close, looks normal from outside, but still has a few grains trapped inside?\n\nMy gum looks good. \n\nIf the cause of my infection is food trap inside, maybe I will need another surgery to remove them.\n\nThis is the x-ray picture taken in Aug. Can x ray show food trap?\n\nWhat can I do to make sure that there was no food left inside?\n\nThank you very much!
