When the gums will form after WT removal

I extracted my upper right wisdom tooth on July 1st week. No stitches. It was erupted tooth. OMFS said no stitches required. I went for follow-up after 2 weeks. I had lower jaw pain and swelling before the extraction. I have the same symptoms after extraction. During follow up, he says the site healed. It's been 8 weeks now. I feel some soreness pain in the extraction site. Is this normal? When I run through my tongue over the extraction site, I see the hole is closed. I couldn't see further in the mirror though. I see some gap between the second molar and the extraction site when I run over the tongue. Is this normal? It doesn't feel like gum formed and a little gap which feels different when I run over the tongue. Is that space normal or the gum form later in between the molars? I could feel some gap between the extraction site and second molar which is not feeling like hard gum and feels like loose gap. How long does it take to form gum at all sides? Is this normal or should I check
