Hello! I removed my widsom tooth 2.5 weeks ago and the dentist removed the stitches and told me to be carefull to not let any food in the hole. I am eating on the other side and rinsing my mouth with salt water after every meal. But recently there is a white thing on the side of the hole and i cam't decide if it's food or something normal. I have tried rinsing it but it wouldn't come out , i'm scared it will be infected if it's food. Please help!
