I had a molar extraction with a bone graft. The stitches were removed earlier today and now I have a hole after eating (Photo)

It can be normal to temporarily have an indentation where a tooth was removed. What is more important is how the bone graft is healing and being replaced by your own bone. An x-ray will be helpful but you need to wait several months, and this process is somewhat slow. If you are concerned, ask your dentist and have him take a look.
