Bone graft fell out 4 days post op, what should I do? (photos)

I suggest 10 days of liquid diet. You should see your dentist as soon as possible for regrafting. 

Hi There,  with healing issues, you want to see your dentist right sway.  Time is critical.  The longer you wait, the less likely you will be able to get another graft in there.  Eat soft foods, don't brush and minimizes sneezing.  When you call your dentist, tell them it is an emergency and you want to be seen today.  Good luck!
