Try Crest Pro Health Whitening Toothpaste, you will be glad you did!
I went on a mission for Smiley360 and received this Crest free to try out.  The toothpaste is a nice minty gel so there is no gritty taste as you brush your teeth.  The mint flavor leaves my mouth feeling clean and refreshed after brushing.  It last for about an half hour if I eat something or drink something.  It has made my teeth whiter than they where.  I am very pleased with this product and thanks to Smiley360 I got to complete the mission.
