Crest guarantees that you will see results within 3 days. The strips are very easy to use. You just put the strips directly on your teeth and leave them on for 20 minutes a day, for 20 days. Easy peasy lemon squeezy!
I have always wanted to try the Crest White Strips. I am a huge coffee drinker (what nurse isn't??), therefore my teeth are pretty...not white. I don't like to say yellow, but they are definitely NOT pearly white.
