The claims of a "whiter smile in 7 days" seemed a little exaggerated as I tried the product for a few weeks and noticed no discernable whitening at all. It leaves an odd taste, not like most other mouthwashes, and I always felt like I wanted to have a good rinsing with water afterwards (although I did not do that in order to truly test the product!).

I did not find it effective at freshening my breath either, again compared to "regular" mouthwashes on the market. The concept is good but, for me anyway, it just did not deliver.

I liked it well enough, it did improve the whiteness of my teeth somewhat.

I received the Crest 3D White Multi-Care Whitening Rinse as part of the Product Review Club. I think it worked well, although the whitening effect was minimal. Slightly helped minimize coffee stains on my teeth.

I can smell/taste the hydrogen peroxide after use. Along with Crest's 3D toothpaste, I began to see results after using them for 1-2 weeks. and i like it without alcohol

im a big coffee/caffeine drinker and was pleasantly surprised that my yellow stains had gotten lighter. not considerably, but definitely noticeable.

the rinse worked well however did not quit like the taste of it. my mouth felt clean and fresh afterwards. it did the job well.

I got this mouthwash with the vivid white toothbrush and toothpaste and I found that using all 3 together did a great job of perking up the whiteness of my teeth in just a day or two. I wasn't expecting much to be honest because I've always poo-pooed whitening toothpastes thinking they were a gimic. I never would have believed a mouthwash would make any sort of difference. But I was proved wrong. My teeth are whiter and I feel like I can go longer before my next whitening as a result.

I really like the concept of using products to keep my teeth white in between using the strips because they look so great at first but a few weeks before you have to do it again, they don't look so hot. This is a really easy way to keep my teeth looking great all the time.

The one thing I have to say about the rinse though is that I wasn't a huge fan of the taste. It's mellow, which is nice, but not as refreshing as I was expecting.

This is a decent product. I wouldn't say its amazing in terms of whitening, because honestly, the only thing that works for me is whitening strips. But as a rinse its pretty effective. Not completely horrible taste, pretty tolerable actually. I would recommend it as a regular rinse but not a whitening product.

Love the scent and it really helps to get off my coffee stained teeth

It works! I’ve been testing out Crest 3D White Multi care rinse, and have seen a noticeable difference in the color of my teeth. I am a HUGE coffee drinker, and smoker. So, unfortunately I have to deal with stains on my enamel. I didn’t want to go the professional whitening route, and instead opted to test out Crest 3D White Rinse.
Big difference, the rinse taste is gentle, and easy on my sensitive mouth.
This product is a definite staple in my bathroom from now on.
Pleasantly surprised folks!
