Great value for the price
I have been using the Crest 3D white toothpaste for years and recently I tried the Luster Now Sensitive teeth whitening toothpaste.  I was impressed with the Luster Now brand but it is kind of expensive for how little you get in the tube.  The Crest 3D white makes my teeth kind of sensitive, but still works well after using the Crest Professional Effects whitestrips and the mouthwash that goes along with it.  I decided to try the Colgate Optic White because it was on sale and I had a coupon for it.  I was impressed with how fresh and and minty it tasted since a lot of different whitening products have a little bit of a strange taste to it.  My teeth started looking whiter in only a few days after brushing with this once in the morning and once at night before bed.  I am really picky about my teeth and very vain (I admit it) and if they do not look white I freak out!  This stuff is one of the few products that doesn't make my teeth sensitive!  Cold things don't make my teeth sensitive at all I was really impressed.  This is one of the best, low cost whitening products that is out there on the market right now.  I would definetly recommend to anyone who wants just a tad whiter teeth, since the results aren't that miraculous.
