Bone loss with advanced periodontal disease

My question is in relation to bone loss. What are bone loss risks of keeping my teeth as long as possible with advanced periodontal disease? Will a fixed bridge or partial salvage, slow, or stop the current bone loss. I have had 4 opinions. Most say to keep original teeth as long as possible. I have had issues in the past with bubble type abscesses if you will, but have not had any issues for 6-12 months. Thank you
