Not sure I'm reading this correctly. Do you mean you have a dry socket? Is this why there is some uncovered bone? I've had a dry socket, and it is incredibly painful, so if that's the case, I'm surprised you made it through the w/e before going back to the oral surgeon. Basically, you get a dry socket when the blood clot gets dislodged after the extraction. I lost mine because I threw up afterward and out it came. I was also cautioned against using a straw, as the suction might dislodge it, too. I had to go back to the dentist the day after my dry socket started. I was practically babbling from the pain.
So, I'll tell you what he did for my dry socket. He used these horrible smelling (okay, not horrible, but very strong) strips of cloth that were soaked in clove oil. This was used to pack the dry socket. I had to have it removed at some point, maybe 2-3 days later, at which time it was packed again. I think it was maybe a week all told before the packing finally came out. I probably did some salt water rinses, etc., after that, but it was so long ago (25 yrs or so) that I can't remember all the details. But I sure do remember the pain, the packings, and the lovely taste of clove oil. Don't get me wrong, I like the smell of cloves (eugenol oil), but tasting all day every day and having everything you eat taste like it gets a little old. I also remember my tongue almost feeling numb from it. Maybe they put some anesthetic in there, too, besides the clove oil.
There are mouth rinses they can prescribe that promote healing. My current dentist is fond of a brand called Nature's Dentist (or Natural Dentist). I spent months swishing that stuff after I had a crown lengthening procedure. It's is pleasant tasting, so it's much easier to comply. My oral surgeon gave me something called chlorhexidine - an extremely nasty medicinal tasting mouthwash designed to prevent infections - when I had my dental implants. But if I had a choice, I'd pick the Nature's Dentist. Not sure if you can get the Nature's Dentist in drugstores. The dentist has always given it to me.
