Extraction/Graft #18 on 7/5, increased pain 7/9 sutures fell out, plug fell off. Is it okay if the hole is not covered? (Photos)

Had #18 out 7/5 in AM with graft for tooth that had failed RCT and infection. Started having pain increase yesterday. Controlled with Motrin and Tylenol. The plug fell off 7/6 in the PM, sutures are completely out. Have had a couple of bone granules pop into mouth. Saw my dentist this AM, he didn't seem too concerned. Having me use Peridex BID and started Augmentin 500 TID today. There seems to be nothing covering the hole. Is this ok? There seems to be redness. Pictures provided Thank you!
