Teeth are brighter!
These strips stick to the teeth well, without slipping around. They don't taste bad at all either! The taste is a kind of mild coconut flavor.<br />I have used whitening gel pens in the past and after a few days of use, experienced slight gum discomfort...I didn't experience that with these strips. I did have very, very mild tooth sensitivity around Day 5 but it didn't last long.<br />I'm a coffee drinker and of course, that stains the teeth. My smile was a few shades whiter after using these strips the full 7 days, so I was happy with that! :)<br />I only took a star away because the directions on the back of the box contradicted the "helpful tips" listed on the included pamphlet. On the directions, it says to brush teeth, then apply the strips, and the "helpful tips" say to not brush teeth immediately before applying strips.
