For hard teeth stains, this doesn't work
I purchased this product from Wal-Mart because of the price.  I was anxious to use it and I did the next day.  After I used it, I stared at my teeth.  At disbelief.  This didn't do what I thought it would do.  I'm a heavy tea and pop drinker and years of drinking these two are starting to show up on my teeth and yes, it's an unpleasant site.  It makes me look like a smoker and I'm not.  I used this for a week and my dark stains are still on my teeth. I thought maybe I should leave this on my teeth for a few more minutes and rinse and see the results...Nothing.  It still looks as if I chewed an oreo cookie and that's not good.  This is my honest review.  Maybe it works for people who aren't tea and pop drinkers.  I just know I'm both of those and it doesn't work for me.  Thus it's sitting in my cabinet collecting dust.
