I like keeping my teeth in good shape. Although my teeth aren't the whitest that I want them to be. They still are not a bad color, but I want them whiter then what they are. I love my teeth. I can't stand when they are an off color.
My boyfriend recently bought me the "Crest whitestrips advanced seal" whitening strips. I have only been using them for about a little over a week now but I can honestly see a difference in the color of my teeth.
There are two strips that you use each time you use these strips. There's an upper strip for your top teeth and a lower strip for your bottom teeth. They are easy to apply on your teeth. They do feel a little uncomfortable to me though. You have to keep your mouth pretty much shut so the stips don't move. The gel feels kind of funny to. I keep them on for about 25 minutes. I forgot how long it says to keep them on because I threw the box away but it's around that long.
Other then that, I would recommend these to anyone looking for some good teeth whitening strips.
