Actually the flavor and the texture of Ollie are way better than any other toothpaste I've used. I love that. But I'm horrible about brushing at night - mostly because I get home from work and crash immediately in my recliner. So I'm not noticing the whitening aspect of Ollie yet. The sensitivity, especially to hot, definitely seems to have diminished. It's slight, but noticeable. If I used it more often I may see more significant results, especially in the whitening area. I just need to find a way to avoid my recliner after work. No easy task.
