I just got a wisdom tooth out that was impacted. It took a while for the bleeding to get under control. After I left they told me to bite down on gauze for 30 min, then change it and bite down again for 30. They said after that it should be under control. well it wasnt so they said to get some gauze wet, bite down on it for 30 min and then change it and bite down for another 30 minutes. well it stopped bleeding as heavily but i am still having some blood. is this normal? they told me to stop using the gauze unless the bleeding gets heavier again. I thought i was supposed to use gauze til it clotted?
