Tastes and smell fresh and does a good job whiteing teeth.

It did work for a while after smoking for over 8 years I recently just quit. I guess smoking will contribute to tooth decay. At first this product did work very well for whiting. But after a few months I started to notice white deposits on one of my teeth indicating tooth decay. I have read that since it contains the same ingredient as whiting strips it takes some wear on the enamel coating protecting your teeth from decay. Anyhow, works great for whiting. If your enamel is strong enough I suppose this product won't have any bad consequence on your teeth or oral health.

I liked this toothpaste, but I like the Crest one better, but it worked really well for me.

I like the "taste" of this toothpaste; however I haven't noticed its whitening effects. A dental assistant has told me to smear it over my teeth and let it sit for 3-5 minutes before rinsing... she claims that it works for her. I haven't tried that yet as I have somewhat sensitive teeth. But one of these days maybe I'll give it a try.
