Active bleeding from a tooth extraction usually stops in about thirty minutes, and some blood will ooze out for one to two days. The hemostasis of the extraction socket after tooth extraction is by clotting, which generally takes thirty minutes. Therefore, after a tooth extraction, the patient will usually be asked to bite a gauze roll at the extraction socket for about thirty minutes before removing it. Theoretically, if the patient’s clotting mechanism is normal, there will be no more active bleeding at this time. However, within 1-2 days after the extraction, the blood clot in the extraction socket is unstable and some blood may still seep out. How long a tooth extraction will bleed varies from person to person, so it is recommended to consult a medical professional.
