3.0 out of 5 starsGood but not Excellent

I wanted to try the Crest 3D Whitestrips on my already pretty white teeth. These worked for sure, but they didn't take my teeth to a level where they were really white, just pretty white. I did cut each strip in half so I could extend the life of these strips and save some money and I will be using them again in 6 months -- maybe I will see more of an effect then. I am a daily coffee drinker and honestly, the strips did get rid of some of the darkening that coffee has done to my teeth, but nothing really more than that. I would recommend if you are starting off with a more yellow natural shade or have been a coffee drinker for longer than I have (>4 years), but if you already have fairly white teeth, don't expect a miracle.
