Wisdom Tooth post extraction? - tooth extraction and bone spurs

# 17, it was about 4 days. Did not really hurt, but I saw today because the bleeding was here and there and I saw a white film on the top of the rubber on the back, and was felt as soft as my chewing gum? I thought that the bone spur, but not secure.
its white and it looks like a Marshmellow on their definition, no food.
any ideas.
