4 wisdom teeth taken out and one extraction sight is still bleeding a little bit and its been over 27 hours later. it's causing pain. normal or not?

Should be Okay: A small amount of bleeding this soon should still be okay but i would recommend following all post-operative instructions from your dentist. Consider biting down on some gauze for a good 15-20 minutes. Also make certain to only eat very soft foods (shakes/soups) and avoid straws until more healed. Call your dentist or oral surgeon's office for any further recommendations.

Probably: If the site is still bleeding you can try biting on a moist teabag. In terms of pain, that is normal a few days after extractions. If you notice any unusual swelling or other symptoms you should see your doctor soon.
