When you want to try the Crest Whitestrips, you have a few choices. There are different types for different lifestyles. You have to decide what you have time for and how much you have to spend. No matter what type you choose though, they should work well for you. I am one that hesitates to spend a lot of money on something that might or might not work, but I was not disappointed. As long as you follow the directions when using your Crest Whitestrips, and use them for the time recommended on the package, you should see a nice difference in the color of your teeth as well.
