Is gum swelling normal for #1 after #2 got extracted and bone graft?

You may have gotten some food or debris trapped in the gums causing the swelling. If you aren't having pain in the bone, the socket and extraction sites are most likely fine. You could have a stitch still in there trapping plaque and causing inflammation. I would suggest you see your dentist to check it out. It isn't "normal" to have swelling this far after the extraction. But that doesn't necessarily mean something is wrong.
