Doesn't work for me :( [SEP] I saw the reviews for this toothpaste and decided I would give it a try instead of paying my dentist for expensive teeth whitening. I also opted for this one over all the other brands because for years, the only brand I use Colgate Total.<br /><br />I grabbed 2 tubes, because they were on sale, and have already used 1 whole tube and have started on the second one. I can not detect ONE ounce of difference, neither can my dentist's assistant. My teeth are the same color as when I started. I'd understand it not working if my teeth were extremely discolored but they are only slightly discolored but still very noticeable to me (curse my childhood of drinking teas & cola!!! lol). I even bought the special 360 Optic White toothbrush (which I absolutely LOVE btw) because it was supposed to help with the whitening but still a no go. :(<br /><br />It's a good toothpaste, as a toothpaste, but as for whitening, it doesn't work. I'm glad that it's working for other people but it has not worked a lick for me which is a bummer I really had high hopes. I guess I will finish this current tube and go back straight back to my Total.  If your looking to buy it, I would give it a try because even though it didn't work for me, it might work for you.
