Teeth whitening strips or gel does it Work?

Well i brought a teeth whitening gel for my teeth and sadly it didn't really work so how about the strips do they work and what do you recommend?
--------------------
They do work. I used Crest, but for a more dramatic result professional is the way to go. Crest is inexpensive professional is run about $300-400, but professional is a bit harsher a home remedy you can try and it does work is Peroxide and baking soda it works http://www.recipezaar.com/recipes.php?s_…
