ColgateOptic White Whitening Mouthwash with Hydrogen Peroxide, Alcohol Free, Icy Fresh Mint - 32 fluid ounces (3 Pack)

This product whitened my teeth within just a few days. I noticed the coffee and tea stains disappearing and I love my renewed smile.

I really like this product. It will be my new Go-To mouthwash moving forward (as long as the price remains steady). Great taste.

This keeps my teeth white like my white shirt.

it did a good job of brightening my teeth

If you are patient you will notice a small difference. I use this after using the toothpaste twice daily

My favorite mouthwash. I use this twice a day and it certainly appears to keep my teeth white and feeling fresh. The three pack is a great deal and I find this to be alcohol free and helps with maintaining your teeth looking clean and white. Most highly recommended.

Works, tastes great and I use it with the toothpaste too. Multi pack has large bottles. A keeper!

I have been using this for almost two weeks and I have definitely seen removal of staining on my teeth in just that short time. I had started drinking loose leaf green tea which was the reason for my sudden tooth staining after I had just had a dental cleaning, so I knew where the new staining was on my teeth. I can see that some of it is completely gone and other areas are getting lighter. My teeth also just look whiter. I will mention this after reading some of the negative reviews: It contains peroxide which has a distinctive taste, which anyone who has ever put peroxide in their mouth knows. So it doesn't taste like sweet mouthwash, but I don't find it horrible either. I don't find it hard to swish around my mouth for 60 seconds even though I am not a fan of the taste of peroxide. Also, yes, it leaves what some are calling a "white film" on your tongue, but that is the sizzling of the peroxide and it goes away quickly. Neither of those "complaints" are enough to make me stop using the mouthwash along with the toothpaste. I do not use their toothbrush, since I use a sonicare electric brush. So far, I have not had any gum discomfort, just the positive whitening effect.
