The conservative approach is a good plan for you in waiting until that 8 week period has passed. Here’s what you can do to see if the bone is healing. After 8 -10 weeks, have an xray done of that area. The bone won’t have filled in completely but it will show up on the X-ray by then. If it has and you have no pain, then you could go ahead with the other 4 teeth.

In the meantime, you can contact that new dentist and have a preliminary plan for when you do make the plunge. 🙃He/she might have some more options for tooth replacement and dentures for you to think about. I’m always happy to help clarify things for you any way I can but the final decisions are made between you and your dentist. ☺️ How’s that for passing the buck?

If I can encourage you in any way, it’s to stop fretting about necrosis in that area. It’s statically low that it will happen and generally it’s more related to lower jaw than upper. Also, the fact that you had a fair amount of bleeding says that there is a good blood supply to the bone in the extraction area. Osteonecrosis happens when the blood supply to the bone is interrupted and it’s surgically repairable if it does happen.
So try to relax about this and let nature take its course. If I could I’d reach through the computer to give you a hug and infuse you with my sense of calm. 🙂 That’s on my insides! Haha outside, I’m animated and flail a lot when I talk.

I have to ask, with only 4 teeth on top you’re so calm about that! What are you able to eat?
