I had my upper left molar extracted 3 days ago. Today a little piece of gum (I guess) fell out and it stunk. I also feel some liquid coming out of my socket I don't have any pain. But I'm really worried I might have infection due to the bad taste also. I do salt water rinse 4 times a day and after I eat I also brush my teeth 2 times a day. I also noticed a black hole in a tooth in the opposite side of my mouth! Can it be a reaction from the extraction? I'm really freaked out! I have never gotten a tooth out.
