Forget it The amount of stannous fluoride in a tube of topothpaste is so minute that it is not worth the time and effort to do it. You will get an impractical amount. Fluorune is highly reactive & poisonousshould you succeed in extracting it.

I'm not sure why you want to do this...if it's because you have little kids that swallow the toothpaste, then you can use toothpaste wo/ fluoride that's made esp for kids. Often has a bubble gum flavor so kids like it. I believe Oral B has some, but I think several brands do.

you would need to heat the toothpaste to a temperature at which either the fluoride will liquefy or everything else will. when this happens, using the emirical formula for each ingredient, determine the varying levels of density. remove each consecutive layer, and keep the fluoride layer.

I don't know but did you know that bottled water has no fluoride. Probably everyone but me knew that. My dentist says his business has boomed over the last few years because of bottled water and the lack of fluoride in it.
