Should Bone Graft be re-stitched? Can it continue to heal if the incision is slightly open? Antibiotics are finished (photo)

6 days ago I had my back molar extracted and a bone graft in preparation for a future dental implant. The sutures are dissolving and it appears the area is opening slightly - a shadowy crease. Over the last few days I have found two small bone pieces (I'm assuming from the graft) in my mouth. I still have a dull ache, but nothing Motrin cannot handle. Should the area be re-stitched? I don't go back for my post-op visit for 5 more days and my antibiotic runs out tomorrow.
