No more bleeding after 24-48 hours after wisdom tooth extraction. If the wisdom tooth grows in a more positive direction and is aligned parallel to the front teeth, and no major trauma occurs during extraction, a small amount of oozing will occur in the alveolar socket, and a blood clot can be formed after 24 hours to reduce the bleeding amount. If the wisdom tooth is buried and obstructed, operations such as cutting the gum, separating the soft tissue and removing the alveolar bone are performed during the extraction, which will cause a large rupture of capillaries and tearing of soft tissues, resulting in more trauma and bleeding, and the amount of bleeding can be gradually reduced only after the blood exuded forms a larger blood clot to cover the wound within 48 hours. After tooth extraction, it is necessary to bite tightly on the hemostatic cotton ball or gauze roll to compress the blood vessels to reduce bleeding. If the blood does not clot for a long time, external Yunnan Baiyao or oral Panax notoginseng powder can be applied to speed up the clotting speed.
