Hi, i had a back mollar tooth extracted due to me having a previus root canal there that got infected. The extrated tooth was the tooth that had the root canal done before. Ive had a blood clot there and been doing everything possible to avoid contact with it. How ever it is now the 3rd day after my tooth extraction and the blood clot has a small fissure in it near my gum wall area. Its a small pocket that started small and manage to get a lil bigger today. Is that normal? Am i at risk for a dry socket? Ive not eaten anything big or hard. All ive eaten is (ice cream, applesauce, yogurt, mash potatoe) and on the day of extraction i didnt eat anything till 24hours later
