I have been using this toothpaste for a couple months now and I have noticed that my teeth are in fact whiter. The toothpaste hasn't taken away all the stains, but it does keep my mouth feeling fresh.

This is one of my favorite whitening toothpastes. It has a light minty taste (not one of those mints that makes your mouth burn!), and is great as a maintenance item to keep your teeth white. I don't often use whitening strips, but I find that this toothpaste keeps my teeth white and shiny as those who use them frequently. Also, this doesn't make teeth overly sensitive, like I've noticed some whitening toothpastes do.
My only complaint is that this kind of toothpaste is a bit pricier than some of the other whitening types, but I prefer the taste and texture of this brand to others that I have tried. You only need a small bit of toothpaste for your whole mouth, so perhaps it's a bit more concentrated than some of the other toothpastes I've used.

Is the packaging amazing or what!? I love it. I also love how this makes my teeth at least 2 shadeswhiter above what they were before I used Optic White. It also tastes great and leaves my mouth feeling and tasting fresher and cleaner. I only use it for 30 days straight and then I go back to my regular toothpaste, as Colgate recommends this. Otherwise, you could strip your teeth.

Best Whitening toothpaste on the market. It's always on sale, and the results are awesome!

I love how much whiter my teeth look after using this toothpaste after such a short time. i would recommend this to family and friends.

I saw a difference in just 14 days. I was also asked if i had my teeth whitened professionaly!!

I love this product. The price is excellent and so is the quality. I noticed my teeth becoming more white within one week of using this product and the taste is great.

My boyfriend and I have been using this toothpaste for about a month now, we both really like this and agree that we have seen whitening results! I have already repurchased this for our household, and plan on using this toothpaste exclusively from now on. Good taste, leaves mouth feeling clean and whiter!

Only bought cause had coupons, tastes bad but it does work, my teeth are getting white

I tried this product because i had a coupon. I was sceptical, I've tried other whitening toothpastes without any noticeable results. WOW, after using it only 2 weeks, I had a dentists appointment, and she asked me if I'd been bleaching my teeth because they were so white! I'm convinced --- this is the only toothpaste for me!
