It works
So I do all the things you aren't supposed to do when trying to whiten your teeth.  Things like drink coffee,  red wine, have a cigar, dark  pop etc etc.  Well this product has helped immensely with the "ewww" issue I had when I looked at the results of the punishment I have put my teeth through.  I use it once in the morning and then at night. It leave my mouth with that fresh minty feeling throughout the day and night.
