Tastes TERRIBLE
I used to love this stuff but I just bought a new bottle and it tastes terrible! I will no longer be using this product.

Good alternative
For a non toxic alternative- it does exactly what it’s supposed to do! However, it gets some “getting used to” flavor wise

Puke
Tried for the first time today and it was so beyond bitter and left a taste in my mouth that genuinely made me wonder if i had just thrown up. Terrible

Something has changed…and it’s not for the better!
This has been my go to mouthwash for several years. Just opened up a new bottle yesterday and upon using, I like many others recently, experienced the worst taste of what I can only describe as the aftertaste of PUKE/VOMIT!! The expiration date on the bottle is 10/2027 so it’s still very much in date.

New Formula Tastes SO BAD
I’ve used this mouthwash for over a year but this latest batch tastes SO NASTY. The aftertaste is literally vomit. I’m so glad other people in the reviews are corroborating this because I thought it was just me.

Good for sensitive teeth!
[This review was collected as part of a promotion.] This works on my sensitive teeth to whiten and remove any bad breath. It’s quick and easy and I use it just before running out the door. It doesn’t leave the film in your mouth I find a lot of other whitening mouth washes do.

CONTAMINATED BATCH, AGAIN!
For the second time in a year, I bought contaminated bottles. The product was cloudy and literally tastes like vomit mixed with, what I can only imagine is, urine. Usually all is fine but the quality control here is absent. Shame on you people! NEVER AGAIN!!!

I don’t know why others hate the taste, I personally really like it and look forward to it. Freshens breath wonderfully and I’ve genuinely seen a difference on two old stains I had on my teeth. I have super sensitive teeth so I can’t use any of the usual whitening products…. Granted this improvement was over the course of like a year of using this, and it wasn’t like night and day, it was gradual and realistic. I drink espresso and wine so I’m happy!

NEW FORMULA = PUKE
I’ve been a constant user of this product, until a couple of months ago when I felt that the taste was different. Turns out they switched the formula but it was still bearable until two days ago when I repurchased this same product and it tasted like straight up PUKE!!! I’m not sure if it expired while on the shelf or what but I could not get that DISGUSTING TASTE out of my mouth!!! YUCKKKK! Very disappointed and I hope they go back to their original formula pleaseeeee

Rancid taste
The taste is foul. I wouldn't serve this to my enemies. Tastes like bleach mixed with rotten fruit. I had to brush my teeth immediately after to stop gagging. Zero stars if I could.

Horrendous flavor.
Believe the othet reviewers when they say that the aftertaste is bad. The person who said it tastes like soap and vomit was spot on. I cant believe they approved this for production and distribution.

More like Musty BaseMint
This mouth wash does what it’s supposed to do, cleans and whitens teeth, but the flavor is a little rough. Fortunately, the taste goes away quick.

Not for Crowns
[This review was collected as part of a promotion.] I have crowns and was unsure of whether or not it would work so I tested. I must admit that I didn’t use it as much as often as I should have. The taste is a lot more potent that the others I used from the brand. I didn’t notice any whitening for my crowns.
