I'm at the very beginning of this journey. I've been diagnosed by Rheum for PMR and suspicion of GCR. I started on 60 mg. Prednisone in January and quickly reduced to 40 mg. I've begun tapering. A few weeks ago I was leaning on my cheek with the palm of my hand when I felt something shift and move around in my mouth. It was an old ill-fitted crown which had cracked off at the gum line along with the tooth. I now need an extraction.
While my situation is not as complex as yours, my dentist will only extract if I get a bone graft as well to preserve the ridge line. Why?

Well...first, Prednisone increases our risk of infection. Second, I now take Eliquis for AFib which is a blood thinner and could potentially make it harder to stop the bleeding and third, I've been on monthly Boniva by mouth for a couple of years. That concerns the dentist the most. And I think that may be because of the rare event of jaw necrosis which seems to be a greater risk with infusion. Is that possibly the issue with you rather than PCR/GCA being the cause?

By the way, as an aside I had a parathyroidectomy 20 yrs. ago. When I started having PMR symptoms it was very reminiscent of the way I felt when I developed hyperparathyroidism. I also have idiopathic small fiber neuropathy which never caused me more than numbness and tingling. That now borders on pain.

None of this really confirms anything other than I'm fearful of losing more teeth.
