We bought this just to try it out my wife uses a sensitive type toothpaste most of the time and she was looking for a less expensive alternative. The Natural White Sensitive Extreme performed well, it did a very good job of DE-sensitizing the teeth. I believe it worked as well as her previous product did. I do have one complaint with the Natural White Sensitive Extreme and that is the taste, it's not really bad but it's not good either, it's a little soapy tasting to me. The taste is not bad enough to keep me from continuing to use the product. Over all it is a good product it does what it should, it just doesn't do it the the way I think it should, and that would be do it's job and taste good. It is a good product and I will most likely buy it again.
