hello everyone,

yes, stannous fluoride can stain your teeth over time... i did a search for each type of fluoride david listed above to learn more about them and many people complan about the staining. trying to remove the stains and whiten your teeth afterwards may pose problems too... whitening treatments seem to increase the chance of cavities.

and i learned that the 1.23% APF fluoride ion leave etches over porcelain over time. :-/

someone has been incredibly kind to procure me a tube of 1.1% neutral sodium fluoride. i can't wait to get it!

i will still have to somehow find a way to get my mom a regular supply for the future, but for now, this one tube is a life-saver!!!

soo.
