Roots removed and bone graft, stitches removed: my gums are open with white stuff coming out, is this normal? (Photos)

I had my 2 roots surgically removed 2 weeks ago and bone graft in preparation for implants, the stitches were then removed 4 days ago and my gums look open. One of them has a soft white thing protruding out and the other just looks open to the elements so not sure if this is normal. Does this look normal? Please see photo.
