2 back lower teeth with wisdom got pulled 4 days ago.bled for hours and seems like a large longhole.can this fill in on its own?i dont see how it can.

Yes: Yes it will fill in. However the dentist should have give. You directions for you do not want to develop a dry socket which is very painful. Use some gauze soaked in saline fold it up and out it over the area where the teeth were removed then bite down and keep it there. That will help you

Dr Malerman agreed

Healing: Extracted teeth leave sockets that fill in over time by first forming a clot and then bone develops into the socket from surround bone and epithelial cells (gums) creep in from the sides and cover the socket. It is similar to when you break a bone and get a deep gash in your skin. Mother nature is amazing at healing our bodies. Check with your dentist if concerned.

Dr Malerman and another doctor agreed

Probably : It will heal eventually but prolonged bleeding without some kind of bone graft may result in alveolitis that takes a long time to heal. Check with your surgeon to evaluate healing and possible options and expectations.

Dr Malerman agreed

Post surgery: After extraction clot forms which eventually fills in with bone and covers over with gum tissue. Not having teeth to support, however, the bone/gums gradually shrink. Did Dentist or Oral Surgeon who did the extractions give you written post-surgery instructions? Before the surgery was there a discussion with your Dentist about replacing the now missing teeth? Talk to your providers.
