If the wound keeps bleeding after wisdom tooth extraction, it is generally abnormal. After wisdom tooth extraction, although it is more traumatic, in most cases, the blood clot will be formed initially in about 15-30 minutes. At this time, the amount of bleeding will be significantly reduced, and the doctor will also give the patient pressure to stop the bleeding within this time, so the bleeding will not be particularly obvious after the operation. Even if there is slight blood in the sputum within 24 hours, there will be no obvious bleeding. If it occurs, it is recommended to go to a specialized stomatology department for secondary treatment, which can generally take the form of local compression and application of topical medication. If the bleeding still cannot be stopped, stitches can be applied to close the extraction wound, which in most cases will not continue to bleed.
