Didn`t whiten my teeth. I am going back to the original Colgate Total. That keeps my teeth really healthy, protected, kinda white. :-)

I don't like much. But that's not bad product.

This toothpaste actually works. It's a shame it aggravated my gums so badly.

I had only used this toothpaste for a couple of weeks and saw results within a couple of days; my teeth were bright and beautiful. Though I had noticed that this started to make my gums bleed and become painful, something that rarely happens to me. As soon as I switched back to my regular toothpaste, my gums were healthy once again. And they aren't even sensitive! Perhaps it had to do with the hydrogen peroxide in this toothpaste.

Overall, this product works, but take caution if it starts to aggravate your teeth or gums. I would rather good oral health over beaming white teeth.

I'm done the whole tube, and I do think my teeth are whiter because of it. Though I don't think I noticed a difference within one week, as the packaging claims.
When I first started using it, I noticed I felt a slight burning sensation. It wasn't exactly painful and I guess I got used to it because I don't notice that anymore.
Now that I think about it, I think it made my teeth slightly sensitive. Nothing major though- my teeth are pretty tough.
To be honest, the thing that made me pick this toothpaste was the packaging. It's strange but I really love the tube, I like the matte texture.
Would I buy this again? Maybe. But I have another tube of something else to use after I finish this one, so I won't be running out to repurchase.
And another thing, I think it is really overpriced.

This is the best whitening toothpaste ever!

I used to use soo many, my recent one was the Crest 3D which everyone raves about..well it did nothing for me.
Maybe it whitened a little bit but the thing is after I stopped using Crest 3D or even switched to another toothpaste, the whitening effect on my teeth would fade VERY quickly..which sucked...

So I tried this one out and right away I noticed a huge diff. hard to reach areas that were slightly discolored were white again, and it's soo gentle I love it. Also, what I do after I'm done brushing before I spit I put some water in my mouth and just use it as a mouthwash for 1-2 mins and that really helps too!
or you can just put some fresh toothpaste on your teeth like you would a whitening product and if you leave it one for a few mins. your teeth are whiter!
I actually had a coffee stain on my white desk and someone told me to use a whitening toothpaste on the stain, I took some of this toothpaste left it on for a few mins. and I kid you not! the stain was gone! I was sooo relived, a coffee stain on a white desk..ah! I thought it would never go away.
This is like white strips in a tube! I can't rave about it enough!

I'm telling you this stuff is the only thing that whitens my teeth!
I only wish more people liked it but I guess we all have diff. teeth and ymmv.

Anywho, will def. keep repurchasing this, love it! white strips in a tube! better than the 5 min. gel too, this stuff is uber gentle, you do not feel it on your teeth. very impressed! =)

I do like this toothpaste, and it's a good thing because I wound up with a ton of it! I had to return an electric toothbrush to Target but I was out of the time window, so all I could do was exchange for dental products. Colgate Optic White was in a 2-for-1 package, so I couldn't bring myself to choose anything else.

Because I have sensitive teeth, I actually alternate this with Sensodyne. However, I've been quite pleased with the whitening effect.

I followed a suggestion I got from a friend: when you're done brushing, spit but don't rinse immediately. Put on moisturizer, blow-dry hair, whatever - but leave it on for 5-10 minutes before rinsing. Much more visible whitening.

I got this product about a week ago. I used to use Crest 3D white vivid before this and regret switching. The taste of this toothpaste is horrible and just tastes strong. My teeth are pretty white already but I didn't notice anymore whitening with this product.

I bought this and had super high hopes for it considering people tease me about my yellow teeth all the time. It doesn't really bother me, since I know it's my fault. I'm super lazy when it comes to brushing my teeth and flossing and all that jazz. (Nasty, I know.) Anyways, I really like the taste of this toothpaste. It makes my mouth feel really fresh and super clean. It claimed you could see "whiter teeth in one week", yeah, not at all. I couldn't tell any difference at all. I've been using it for over a month now and I haven't noticed anything different about my teeth. I am super disappointed and stuck with yellow teeth for now.

I've been using this toothpaste for abut two weeks now and brush 2 to 3 times a day. I've noticed that my teeth do actually look a bit whiter, it's not a huge difference but hopefully it will be after I use it more. The taste isn't the best, but I don't buy it to eat so it doesn't matter to me. I haven't noticed any sensitivity either. Unless I find something better or any of this changes, I'll continue to use it :)

When I first used this toothpaste my teeth felt sensitive right after brushing, I usually never have a reaction like this I threw this toothpaste away makes your teeth very sensitive. I would not recommend this to anyone, I was very displeased with the product overall.
