Honestly I have been a Crest toothpaste user most of my life. |We are planning a trip and I want my teeth looking nice and white. I bought this last week. I'm a huge red wine lover and my teeth are getting whiter each day. Im not sure of the secret that Colgate Optic white has but in a week my teeth are brighter what's not to like.

I actually really disliked this toothpaste. All I tasted was peroxide to the point of it making me gag. I thought it was just in my head but after a few uses it just got more obvious and nasty. Never noticed my teeth any whiter and just wasn't worth it. I don't recommend it and would never buy it again.

I wouldn't tell people not to buy this product, but I also wouldn't recommend it. I didn't find it made my teeth any whiter than when I started out. I also found it had a weird aftertaste, but maybe that's just something I noticed.. I haven't bought it since and i likely won't buy it again.

I liked using this product as just a regular toothpaste, but it did not whiten my teeth at all (and I don't smoke, and hardly drink tea/coffee/wine). It has a good flavour and leaves my mouth feeling super clean, but with no whitening effect, I probably won't buy this again.

I tend to get toothpaste when it's on sale, and I've had good luck with 3D white toothpaste! The value keeps me coming back for more, and the added bonus of it saving my coffee drinking teeth is even better.

My all time favourite toothpaste. Teeth feel extremely clean and they really do get brighter and whiter. I get many compliments on my white teeth and I'm a smoker, so it's working. I got proof

Love this toothpaste ! I actually hid it from the family ,it's mine all mine .I have tried so many toothpastesto make my teeth white ,being a coffee drinker and a smoker I look for a good toothpaste rather than chemicals that can be harsh on teeth and gums ,this is my favorite so far I use it with the mouth wash and makes me teeth ncie and white ,tastes great excellent price and doesn't burn the tongue

I really like this product because I've actually been able to see results! Even after a week I felt I really noticed a change in the colour of my teeth. It's not harsh on my teeth either and your teeth feel really clean after brushing them! My only downside is that It doesn't really have much of a taste I find, but thats not a big issue for me!

I find this toothpaste is pricey when you don't buy it on sale however, really like this product. I feel that it really cleans my teeth and gives me a long lasting fresh breath feeling. The flavour is great as well. Not too strong at all, just right! Plus, it helps to keep your teeth white.

J'ai remarqué que mes dents sont plus blanches depuis que je l'utilise ( Environ deux semaines. ) J'ai trouvé ce produit en pharmacie à prix abordable. Par contre, je trouve la texture et le goût assez étrange. Je ne sais pas si je serais en mesure d'utiliser ce produit à long terme puisque le goût est un assez grand irritant. Pour le moment, je pense quand même terminer le tube.
