Guy with yellow teeth tests out whitening strips for 20 days (Crest 3D Whitestrips)


Update 1 Year Later:
(are the teeth yellow again?)

I have stained yellow teeth. Was recommended crest 3d white strips by a friend and after a year of it sitting in my drawer I decided to use them for 20 days.

I only used the strips on my upper teeth and left the bottom untreated for your entertainment.

No gum/teeth sensitivity was felt during the entire 20 days of use.
