I had been anxious to try a ""whitening"" toothpaste, and had high hopes. However, I didn't feel this product lived up to my expectations. While my teeth felt clean, I didn't experience any noticeable difference in their coloring. This product also didn't leave my mouth as ""fresh"" as other Aquafresh products that I've used in the past. I did see a commercial that said they've come out with a new ""fresher"" version. I would probably not purchase this product again.
