A few weeks after I started using Crest Pro-Health Rinse, I developed brown stains all over my teeth. It took my hygeinist a good hour to scrub off all the stains. Most of the stain came off.

I found multiple accounts of other people experience staining with this product on the internet.

This product should be off the market.

:mad:

I have to defend Crest Pro-Health. It causes staining in y mouth too, but it only stains the plaque that is not removed from your teeth after you brush and floss. I like to rinse with it because any places I missed turn blue and I can go back and clean them. Very helpful with braces.
