Colgate Optic White High Impact White Toothpaste

This definitely whitened my teeth after a couple days of use, which is basically unheard of with all other toothpastes I've used. This is by far the best whitening toothpaste on the market.

I am pretty sure I saw a brightening effect after using this for a short amount of time. I also like the taste of this toothpaste, and I appreciate that it's affordable. I will repurchase!

I do feel like this helped whiten my teeth after regular use but I can't speak to whether it's safe for the enamel, as it claims.
