Hi,
I had a very similar situation. I had two teeth extracted before treatment. One was not so great and came out pretty easily. The other was not bad but it would likely go bad sometime in the future so I had it pulled. It was really nasty to get out.

About 6 months later I started seeing bone show through my gums and it freaked me out as I thought it was ORN. I went to the oral surgeon who felt it was a tooth fragment that was finding its way out. I went back a couple times and sure enough it did finally surface to where I felt the little piece and then it all healed up.

From my research ORN will show up more like a couple years or more past treatment. It takes awhile for the lack of blood supply to finally degrade the bone structure to where it becomes an issue. That is if it ever shows up at all, which is a fairly small percentage. Good luck
