@lmcfm1 - Hi and welcome to Connect!
I have experience with dental bone loss and autoimmune disease. I’m fine now, but a few years ago I had a gastrointestinal autoimmune disease plus a Sjogren’s like illness. Tested negative, but I had very dry mouth and eyes. I ended up having almost see through front teeth, due to lack of saliva I think. I ended up with capped teeth.
Also, if you take a lot of steroids over time there will be bone loss.
I am fine now after treatment with immunosuppressive drugs. No more mouth dryness, just the opposite!
May I ask what you are treated for?
