This was my choice based on my dental hygienist suggestion. I believe this product has worked better than most others I have tried. I started with just a 1 tube purchase, then went ahead and bought the 4 pack.

I bought this toothpaste at Sam's Club. It was on sale and I needed toothpaste. It says on the package 10 X whitening power. I can't prove my teeth are 10 X whiter. I will say I've been using it twice a day and my teeth are definitely whiter. I have not needed to buy whitening stripes. I gave a tube to my sister and she also feels that her teeth are whiter.

This toothpaste really does work about getting your teeth white and keeping them white if you use it every day. And it does not make your teeth get sore or some people say well if you use that it makes your teeth hurt. No, these doesn't make your teeth hurt, if your gums are like problems with them, the peroxide actually heals them that's bleeding gum, toothpaste, and bleeding gum

I like the optic white renewal. It always makes my mouth feel cleaner and my smile look brighter.

Good price, fast service and good quality products.

I started buying this initially for my pop drinking adolescent. It helped tremendously with the color of his teeth.

I was using another well known brand. This purchase was a replacement and a good choice. It works faster. No sensitivity noticed after a months use.

I'm feeling that there is not much toothpaste for the size of the tube. The product is OK but the amount for price is not what it should be.

I've used Colgate Optic White before. This order seem to be different. The product had separated in the tube. Old maybe(?)

Now 0.5 oz less in each tube than the last time I purchased and the price is higher. Also in true corporate fashion both the tubes and the packaging are the same size as before to deceive the buyer into thinking they are getting the same amount. Cracks me up that these corporations preach kindness in their commercials while being the most unkind by deceipt.
