I have been diagnosed with perionditis by (2) dentists and told by both alot of bone loss, I have been told by (1) dentist to extract the botton front (4) the other dentist said deep gum cleaning and home care? I was also told if I get a deep gum cleaning, teeth will start to get loose after Bacteria and plaque is removed?? If that is the case. Why would I need to get a deep gum cleaning, If it would lead to teeth getting loose. I just need an understanding on this.
