I bought this for my son who has TOBACCO stained teeth. Within 2 weeks people were commenting on how nice his teeth looked and they had no idea he was using any product. Used it in conjuction with Rembrant Intense Stain toothpaste. Now my whole family: husband, myself, daughter-in-law are all using it for just normal aging colored teeth. BIG difference. Kindof pricey, but doesn't bother my teeth and make them sensitive like strips have. I also bought for us all the ultra sonic toothbrush. It does help to follow directions and tap the tube on the counter and store it correctly. Not a problem, just nice to know to get every last bit.

I went thru a bottle of this and I see very little difference when it comes to whitening my teeth. It really did not pay to use it. I am using a whitening toothpaste with it so I don't know which is working; however, I expected better results from this product.

I used this with their "age defying" toothpaste and by the end of the tubes they did lighten my teeth a few shades. I'm going to keep using them because they're both inexpensive and a good deal since they work so well.

Very nice teeth whitener - I used to smoke ( quit now - YAY!!! ),so this product keeps my teeth nice and white and it's VERY easy to use. Virtually no taste - my fisrt tube I used morning & night over my Tom's of Main toothpaste, right now only at night ( I'm on my third tube ) and my husband uses it as well. Bought one for mom - she likes it too. I don't drink coffee of soda, but tea and juices,but EVERYTHING stains our teeth. Very nice products - does not make teeth sensitive,not expensive and you don't have to keep it in your mouth for 30 minutes,like whitening strips. I wish packaging was different ( that's why I gave it 4 stars )- tired of banging it on counter! ;) Otherwise - BUY IT NOW! After GoSmile it's my favorite thing!

My husband drinks red wine and the wine was starting to stain his teeth. He is not the type to do anything like the strips, etc. I did buy him this product and he uses it daily and in a few weeks I could see his smile was definetly whiter. Now I am using it too. Just keep it next to your toothpaste.

This product is effective at whitening. However, I did have tooth sensitivity when I tried using it more than once a day. So I did some research. The European Union's equivalent of the FDA says, "The use of toothpastes, mouth rinses and tooth whiteners containing up to 0.1% hydrogen peroxide does not pose a risk to the health of the consumer. Toothpastes and mouth rinses should not contain more than 0.1% hydrogen peroxide." Arm & Hammer does NOT state how much hydrogen peroxide is in this product, so I wrote and asked them. They replied that: "The percentage of Hydrogen peroxide is proprietary." I wrote back and said I was concerned about safety. I only wanted to know whether the amount was less than 0.1%, not the specific amount. They never answered. I still use it occasionally, but would not feel safe using it often.

Left my teeth feeling extra clean, like after visiting your dentist

IT WORKS!!! USED MORNING AND NIGHT. SAW RESULTS IN A WEEK :)
