The following therapeutic measures can be taken when the tooth keeps bleeding after extraction. Use ice or cool towel to apply to the extraction side externally to constrict the blood vessels, slow down the blood flow and reduce the amount of blood exuding from the wound. If the fracture of the alveolar process or the presence of granulation tissue occurs in the extraction socket, the socket can be repositioned and filled with gelatin sponge to promote hemostasis after thorough scraping of the granulation tissue and fracture fragments under local anesthesia. In case of large trauma or gingival tear, the trauma edge can be trimmed and aligned, sutured to close the trauma, and epinephrine cotton balls can be placed to promote hemostasis. If the blood does not form a clot for a long time and the color of the exuded blood is bright red, you can take Yunnan Baiyao or Panax notoginseng powder orally to accelerate the clotting speed.
