I bought the travel size version of this on a recent trip and it wasn’t what I expected. I thought it would be a bland tasting toothpaste that does a mediocre job. It was actually had a pleasant tasting [very tasty, indeed...waiting isn’t eating toothpaste frown upon?] toothpaste and it didn’t have a bad aftertaste. I did find the toothpaste a bit gritty and not as smooth other toothpastes. Overall, it left my mouth feeling clean and refreshed. I am not sure if it actually whitens but I don’t really need to whiten my teeth. My go to whitening tip....don’t smile and it works every time and it’s free!
