After the wisdom teeth are extracted how long should you bite down on the gauze?

Bite down on the gauze, changing it every 15-30 minutes, and when the gauze has just a pinkish tint to it (instead of the dark red blood you had been seeing), then the bleeding has slowed down enough to remove it. Just do not bend over, use a straw, or smoke a cigarette or the bleeding will flare back up. If you should happen to begin to bleed again, simply put some gauze back in your mouth. Try to relax until you have reached the point where the gauze can be removed. Hope this has helped! The bleeding should stop about 20 minutes after the surgery. Although is some cases, especially after complicated extractions, the gums can start bleeding again, and you can also wake up the next morning with some blood in your mouth. It is always handy to have extra coton gauzes with you. If you have none left, you can go to rite aid or daune reade to pick up cotton
