Tastes like a**, but it works.

OMG. It really worked! But what did it do? What came out of my mouth? I don't know but it's gross, so gross. It tastes horrible. But if it helps, I'll plow through. By the by, my gums feel incredibly squeaky clean.

Practical Mouthwash for a Clean and Fresh Feeling

I’ve been using this mouthwash and I really like it as part of my daily oral hygiene routine. What I like most is the fresh feeling it leaves after using it and how easy it is to incorporate into my everyday routine. The bottle is also practical and easy to keep within reach. For me, it’s a good option for anyone looking to complement their brushing routine with a mouthwash that helps maintain a clean and fresh feeling in the mouth. After using it, my mouth feels clean and refreshed, so I would recommend it for daily use as part of a good oral care routine.

Game changer for periodontal EDS. Worth every penny.

The media could not be loaded.









I scrolled across this product on social media & decided to buy through Amazon. Seriously, this is an incredible product & I'll be putting it on autoship once I figure out how long it takes me to get through this first bottle.Although I have not been diagnosed with periodontal EDS yet, I'm seeing a specialist who will know about this rare form & will be able to confirm or rule it out. Since getting my second set of braces (as an adult) my dental health has been nothing but issues after getting them off. My teeth continue to move and break every set of retainers my knowledgeable ortho makes for me.I've never had issues until now, and now my teeth are hyper mobile. I'm doing everything I can to save the integrity of my real teeth which includes regular brushing, more flossing, and everything inbetween.My orthodontist is now having me come in every 3m for cleaning instead of the standard 6m.When I saw the gunk people were claiming this product flushes out, I decided to try it...and they aren't kidding.Now, you won't always get junk left over, but most of the time when I rinse with this, I have a bunch of floating debris. Relieved to have it now, but I think about all the junk over 37y which has just stayed between my teeth after thinking they are clean.The taste isn't the best, but it isn't the worst, either. And personally, I don't care because the product works. It also doesn't burn like mouthwash containing alcohol.All it takes is a tiny capful. The bottle should last a long time. I will try to upload a photo, but just know results are better than the photo gives it credit for - and absolutely, my teeth are whiter which is awesome.

This works!

The taste is so bad but the results are worth it. After just a couple uses i could see the results of a whiter brighter smile.

Works great !! Give it a try

Let me start off by saying I never ever write a review. However, this stuff is amazing!!I brushed my teeth as normal. I even used mouthwash. The extra gunk that ended up in the sink was gross, but the way that my teeth feel and my breath is so fresh five out of five stars would highly recommend.

Wow

Wow, that's all that I can say. Now my question is what the heck coming out of my mouth!!! Eeeeeeewwwwwww!!! I was skeptical, very skeptical of if it would be as the ads proclaimed. 30 seconds and this stuff floated like butterfly and stung the gunk in my mouth like sregical homing bee. I thought my mouth was clean from the careful brushing prior to, but I was so wrong. Now I'm in a rush to reorder another bottle before my current one runs out. Great buy.

Funky aftertaste takes a little bit to remove itself from your mouth

I love this mouthwash it's a little bit on the pricey side but it does help get some of the plaque and extra gunk out of your gums and teeth

At first I was skeptical

Let me start off by saying, I believe no one unless I experience first hand my facts, influencers reviews people lie, but I have to admit this stuff had me curious, so I received it, brushed my teeth, flossed, brushed my teeth again, I do have an expensive electric toothbrush, then I proceeded to use my electric tooth polisher, then I used the mouthwash, yeah that was disgusting I have no idea what was coming out of my mouth and where it was coming from but I have to say this mouthwash does work, my mouth has never felt cleaner, The taste is not overpowering, and now I'm convinced talking to anybody their mouth is straight up nasty unless they use this, buy this it's not expensive and it's worth it, I can tell you first hand

Frescura y sensación de limpieza superior

Deja una sensación de frescura superior, el inconveniente que le veo es la poca cantidad de producto por envase lo que no lo hace opción para más de una persona.

Fresh Breath

So the brown stuff is just the liquid binding to proteins it’s not the “gunk” it’s pulling out. Thats a social media inaccuracy. It is a good product. It keeps my breath fresh and keeps my teeth looking clean.

Not a replacement for dentist, but pretty close!!

If you thought you had white teeth before, you have no idea! This made me feel like I had just left the dentist, in the best way possible, and that was after just one use! Disgusting, but gratifying in the best possible way. 😂 It did sting my tongue a little, but honestly, no more than Listerine, without that terrible Listerine taste. I was genuinely impressed with the results after just one use! I wear night retainers so it is hard to feel like my teeth are truly clean in the morning after wearing night guards all night.

Actually works with the black gunk and everything! Worth a try at least!

I was super skeptical when I saw the ads for this alcohol free mouthwash. But omg it really works! With the black gunk and everything! I don’t take the best care of my teeth, but I made sure to floss, used nano hydroxyapatite toothpaste, and an oil pulling solution to really see if it worked. I ended up swishing twice in one night (since I could still taste some bad breath from my bad tooth) both times came out with black gunk, and felt so clean after the second rinse! I want my family to try it out now! Only bought 1 bottle because I was skeptical, but I’m definitely going to buy the 2 pack next time! It still burns like it has alcohol in it, but this is honestly the cleanest my mouth has felt since visiting a dentist over 10 years ago (parents never took me after that) definitely worth a try at least!

cleans all gunk.

i love this product. it cleans my teeth, helps with a whiter smile, and i don’t mind the taste. it’s a bit strong but after a minute it gets minty. it also removes all the gunk that the toothbrush didint. Perfect purchase. i’ll never regret it. keeps my breath smelling minty for at least 6 hours.

Gross but excellent

This has to be the grossest mouthwash on the market. But that’s what I love about it. No matter how detailed I am when brushing my teeth, this mouthwash always finds gunk left behind. It’s surely disgusting to see all the bacteria poop it uncovers but my mouth feels cleaner and my breath is super fresh all due to this amazing Japanese mouthwash. I bought 3 bottles initially and now just placed an order for 3 more. I usually brush my teeth in the master bathroom but sometimes my husband interferes and I have to brush in another bathroom. So I have a bottle of this mouthwash in every bathroom just in case I need a quick refresh during the day. It’s really amazing that this mouthwash reveals all the goo I missed while brushing. But that’s precisely the point. Highly recommend!

Unbelievable

This stuff is unbelievable. It works like it’s advertised. We tested it with just poring it in a glass and spitting into it just in case it’s like a reaction to saliva or something that makes the weird gunk. I did it before brushing and after brushing and you can tell there’s way more gunk before brushing than after brushing. But my teeth have never been so clean.

Mouthwash

This is a good mouthwash. It doesn’t burn. You do get a little tingle. Now the mouthwash doesn’t burn come out a little darker when you spit it out. Also you with get a few particles that will come out that you did get when you brushed. Please note it’s NOT going to be like what you’ve seen in the videos. If you’ve seen one before on Facebook, Instagram or Tic Tok. Now for me in MY opinion it gives you that clean feeling in your mouth much longer after use than any other mouthwash.

Frequently Asked Questions

Does it really remove visible gunk? +

Yes, the does remove visible gunk. Customers report that it effectively pulls out buildup and debris you can see in the sink, even after brushing and flossing.

The formula binds to proteins and debris in your mouth, using hydrogen peroxide and essential oils to target areas your toothbrush misses—like your tongue, cheeks, and gumline. Reviews suggest it leaves your mouth feeling noticeably cleaner and fresher.

Does it actually whiten teeth? +

Yes, it does whiten teeth. Customers report their teeth have gone "a few shades whiter" and note visible whitening results over time.

The hydrogen peroxide formula works by first removing buildup and stains, which allows whitening agents to be more effective on your teeth. However, reviews suggest the whitening is gradual—it maintains and enhances whiteness rather than providing dramatic overnight results. Some customers mention they didn't notice a difference, so results vary depending on your starting point and oral habits.

The product is designed to "help maintain white teeth," so it works best as part of a regular routine.

What makes this formula different? +

It combines high-strength biotin, collagen, MSM, vitamins, minerals, and botanical extracts like saw palmetto and bamboo to provide comprehensive nutritional support for healthy-looking hair.

How long until I see results? +
  • Immediate effects: Many customers notice a cleaner, fresher feeling and visible gunk removal after the very first use
  • Whitening results: These are more gradual — the product is designed to help maintain white teeth over time with consistent daily use, rather than deliver dramatic instant whitening
  • Individual variation: Results depend on your existing oral hygiene habits and starting condition — some users see noticeable whitening relatively quickly, while others notice more subtle changes

The key is daily use as part of your routine — the cleaner your mouth stays, the more effective the hydrogen peroxide whitening can be over time.

Does it cause tooth sensitivity? +

If you have sensitive teeth, we'd recommend:

  • Testing it for a few uses to see how your teeth respond
  • Starting with shorter rinse times (under 30 seconds instead of the full 60)
  • Consulting your dentist before use if you already have sensitivity issues

The product directions say to swish for 30–60 seconds daily, so adjusting your routine could help if sensitivity develops.
