Crest Whitestrips really work!
I am a coffee drinker so my teeth can often use whitening.  Crest Whitestrips are so easy to use and they really work!  One helpful hint is to have a tissue ready when you first put them on and "dab" the excess from behind your teeth onto the tissue so it doesn't go in your mouth.  If you REALLY want to whiten your teeth, do the whitening five days in a row.  =)
