I decided to try this toothpaste after seeing an ad for it. I love it! I buy it at the pharmacy I work at. I've never thought my teeth needed whitening, but since I've been using it people are always telling me how white my teeth are so I definitely believe it has helped whiten my teeth since I've been using it. It might also work well with the mouthwash I use of the same brand. I highly recommend this toothpaste to everyone!
