Will lighten 1-2 shades which matters when you smile!!!!
I was surprised when I received my order.<br />I ordered the box of 7 treatments, 14 strips, 7 upper, 7 lower.  I received 2 boxes, 4 treatments in each box, 8 strips, 4 upper, 4 lower, each box . That gave me a total of 8 treatments instead of 7!!!!  No dislike.
