I have been using this on the advice of my Dentist. The whitening ingredient is hydrogen peroxide which takes some getting used to the foaming action it creates. but it is the safest whitening mouthwash for protecting your teeth's enamel. I, as well as my Dentist, have noticed an improvement in my overall gum health as well as whiter teeth with less staining.

I have used Listerine Whitening products in the past. Listerine Whitening Mouth Wash promises have the same positive effects of regular Listerine (e.g., to fight plaque, gingivitis and kill germs that cause bad breath) plus a brighter and whitened smile.

Unfortunately, I have found many reviews/lawsuits recently that claim that the alcohols in Listerine cause a drying effect in the mouth (which is the burning sensation you feel which ultimately makes you want to spit sooner than later). Supposedly, people claim it is the drying power that naturally causes cells in the mouth to die, resulting in an increased probability of oral cancer.

Not sure what to make of these recent reviews but it definitely scared me off of any Listerine products for a while!

Warning: Do not use this product it left a chemical burn on the roof of my mouth. This is the second time my mouth has been burnt by this mouthwash; however this time I figured out what was burning my mouth. It is so bad the burn that I can eat anything to tough. I am so disappointed.

Has a very strong taste but leaves your mouth feeling fresh and clean. Kills the worst breathe. You just have to get used to the taste.

I was quite disappointed and didn't find the product worked and my mouth didn't feel fresh at all. I really had higher expectations for this

This product makes my mouth feel so clean.

I really like this product, and I do believe my teeth are whiter when I use it regularly. I also feel like the peroxide, aside from whitening, helps to keep my gums healthier when I'm too lazy to floss. I use this after brushing before I go to bed. I rinse for as long as I can, which generally isn't the recommended 60 seconds, because the rinse IS strong. I rinse with water afterwards, even though that isn't recommended. It probably does increase sensitivity; though, I haven't noticed any major issues despite having sensitive teeth, in general. The whitening effects aren't dramatic, but I definitely believe this rinse helps to combat the staining effects of things like cola.

I recommend it.

I checked this product out when I received a great coupon in the mail. I have been using it ever since! I found that it really helped to whiten my teeth. But, I do notice that my teeth are more sensitive now, than before.

Really like this product. I find my teeth are whiter in a short period of time and my mouth feels cleaner with using this product. Only downside is my teeth started to feel a bit sensitive.

I do not usually use whitening products, but I got a coupon to try this and it really works well. I totally noticed a difference in just a few days of using it. My teeth were definitly a lot whitter. Using this product continuously really makes a huge difference.
