Bleeding should stop automatically within 5~15 minutes after tooth extraction for normal people. If the bleeding does not stop, it is not recommended to stop the bleeding at home by yourself, and you need to consult the doctor in time and choose the appropriate treatment according to your condition, such as filling for stopping bleeding in case of slight oozing or gushing of blood. 1. For minor blood seepage, it is better to fill in the iodoform sponge, which can be dislodged by itself later without follow-up; for faster blood seepage or gushing of blood, it is necessary to fill in with iodoform gauze, and remove it after 5-7 days, so as to avoid removing it too early, which will lead to gauze adhering to the wound and inducing re-bleeding; for bleeding from incision and mucous membrane tear, it is necessary to suture the wound to stop the bleeding. 2. Bleeding at the edge of tooth extraction wound can be stopped by applying hemostatic powder (e.g. Yunnan Baiyao), but it is not suitable to fill in the extraction socket to avoid contaminating the wound and affecting the healing of the extraction wound; bleeding caused by hematological disorders should be treated symptomatically, and coagulants, phenol-sulphonyl ethylamine and other coagulation-promoting medicines can be given to stop the bleeding. When the symptoms of bleeding after tooth extraction, you can go to the hospital in time, under the guidance of the doctor for related treatment, strictly comply with the doctor’s prescription medication.
