i've been using this for about a week, once a day (as opposed to the twice-a-day rec on the bottle), and already see results.

the taste isnt amazing, but its not as bad as other mouthwashes i've tried in the past either. and this one doesn't make my mouth feel like it's on fire so much as others have. as you swish this around it will foam up, so you have to use a little bit less of this than you woudl other rinses, just so you'll have room in your mouth to continue swishing.

i don't smoke or drink coffee or tea, but my teeth had gotten yellowish in the creases in between teeth. switching to an electric tooth brush for sure helped, and i've been VERY happy with Rembrant's whitening toothpaste in the red tube, but i figured a whitening rinse might help. i did NOT like the pre-brushing whitening rinse. it tasted horrible! so i figured i'd try this instead, to be used AFTER brushing. in theory, i guess one could use all 3.

only drawback is that after i spit this out i have to spit a few more times to get all of the foam out of my mouth. but i DO lik ethat it foams up-- makes me feel like its really getting in between my teeth!

i'll for sure re-buy this!

WOWOW oh my goodness! This product REALLY whitens your teeth!...like a noticeable difference in about 2 days? I didn't even think that was possible. So I have had braces on for a little over a year now (yes in my early 20s - how sad..) Anyway, I noticed my teeth have gradually become an unsightly yellow shade since and decided it was time to do something about it.

This product WORKS. I've only used this four times now (once in the morning and once at night - 60 second 15mL gargle). I noticed it is different than other mouthwashes in that it gets really foamy. My teeth are noticeably whiter - and I am definitely not imagining things. I wasn't expecting such quick and dramatic results - talk about instant gratification! I'm honestly a little amazed at how well this product works.

I am extremely pleased with this product and will definitely repurchase. Although I will say once I get my teeth to the shade they were pre-braces, I will take it easy on the mouthwash as I do not want to whiten my teeth to a shade they were before braces! After my braces come off, I will definitely keep using this mouthwash to get an even more super white smile :)

This stuff really whitens your teeth. The only negative is it made my teeth too sensitive :(

My husband and I both use this, and he had fantastic results. I, however, didn't have such good luck. The peroxide in this turned my tongue brown and made all food/drink taste like metal. A quick Google search turned up the information that peroxide can kill off the 'good' bacteria in some people's mouths and cause these symptoms. I was fairly disappointed because the product was easy to use and very price friendly. I'll stick with GoSmile.

you guys should try this, before washing your teeth with tooth paste put some of the pmouthwash in your mouth and brush your teeth (no toothpaste)... I think this achieves maximum whitening...

This is a really great whitening mouthwash. Immediate results for me. It stands out from the others and it's got a very reassuring taste. My teeth were really clean after using this, my breath is better and I couldn't stop giving big toothy grins in each reflective surface. I also like the packaging as it's very shiny and eyecatching. Will repurchase.

Yowza! This review is for what I think is the reformulated version of this -- the whitening *restoring* rinse. I have some acid wear and, for no real reason, wanted to get away from abrasive whitening toothpastes so I decided to try this since it basically relies on hydrogen peroxide to whiten, with added fluoride for cavity prevention. My teeth are naturally pretty white, and in conjunction with borderline obsessive oral hygiene, have minimal staining -- mostly from coffee and tea. I swear -- though I know there are people who will refute it -- that my teeth were noticeably brighter by day 2. Not, like, total transformation white, but what little staining I had definitely seemed lesser. Rinsing with this is far easier than with regular Listerine, as there is very minimal mouth-afire feeling, and my mouth feels nice and squeaky clean after using it. Because of the added fluoride, it is recommended not to eat or drink for 30 minutes after rinsing, which is either a non-issue or a serious annoyance, depending on my schedule any given day, but that's the only downside. I'll definitely repurchase.

My husband and I started using this about a month ago. His teeth were stained from smoking (not anymore!) and coffee. I usually use whitening strips periodically, so mine were decently white - but I was thinking about the strips again. Well, in just these few weeks, we have enjoyed great results! The stains on his teeth are almost gone! I'm not even going to bother with the strips this time around. I wouldn't have believed it - have always had to suffer more for white teeth. I'm looking forward to seeing more results. It doesn't taste very good, but it's not a beverage so I'm not sure that matters. I highly recommend this!

When i first bought this listerine i didnt think it was gonna work i thought it was just advertisment so it can sell.. but belive it or not it really does work.. it takes time but it works..

Just want to warn everyone that listerine contains alot of alcohol, recent reports have shown a small incidence of oro pharangeal cancer when frequently using an alcohol containing mouthwash, especially if you're a smoker. Also, it can soften composite (white) fillings, and make them more prone to stain. A polish by your dental hygienist will be more effective at removing extrinisic stain from your teeth.
