It is not normal to keep bleeding after wisdom tooth extraction, so it is recommended to consult a hospital immediately to find out the cause of the problem and to stop the bleeding. Usually, wisdom teeth are the most difficult and traumatic of all the teeth in the mouth. If wisdom teeth keep bleeding after extraction, it is likely to be caused by gum lacerations, local fractures of the alveolar bone, or the loss of blood clots in the extraction wound. In this case, you should visit the hospital for specialized treatment. Usually, if you keep bleeding after wisdom tooth extraction, you should use gelatin sponge to fill and compress the extraction wound to stop bleeding, and try to close the extraction wound to minimize the exposure of the extraction wound. Then fill cotton balls or gauze in the location of the extraction wound in the mouth and apply occlusal pressure to stop the bleeding.
