I had a dental bone graft 2 1/2 weeks ago. The stitches came loose and were removed 12 days post op. I can now see a gap between the sides of the incision - essentially there is a hole in my gums and the graft is showing through. I'm not sure if it is the bone or the membrane they put over the graft. Will it heal or do I need to call my oral surgeon to fix it?
