Chilli,
I have "moderate-to-advanced" periodontitis. I've been told I had a tooth that was very loose, but it doesn't really feel like it. I think dentists have a different standard of determining what's lose than we do.
I am getting over a major tooth infection and some of my teeth have been feeling slightly loose lately, but I'm not sure how much that's a false sensation. See my comment to Heather on this forum, re: dentures.
I moderate an almost inactive forum and write a column on it with lots of info called "My Periodontitis Diary":

Good luck.
