Hi Rosymonroe - yes, I remember that string as I came across it after my treatment and changed my flouride as a result. I can't figure out how to put in a link, but I think the thread you are looking for is 'Check your Flouride gel'. You could search for that or also search for 'acidulated' which is the type of flouride you want to avoid if you have any crowns, etc. (which is my case).
Best,
Nancy
