Already feel the difference!

BrianneMarch 4, 2026✓ Verified purchase

I got this yesterday, used it last night before bed and could already feel a difference this morning. As an aligner wearer this morning felt drastically different. Used it after brushing last night, put my aligners in to sleep, and when I woke up my aligners , teeth, and mouth felt sooo much better(and cleaner) than usual. Used again this morning after brushing and once this afternoon, now I’m starting to see a whiter smile. The flavor is definitely utility not novelty- but it’s doing its job really well, so I’m. Not at all mad at it!!! 10/10 Read more

Very expensive, and also not wholly accurate in terms of what it says it does...

Very expensive, and also not wholly accurate in terms of what it says it does... A Gentle Reality Check - While these types of mouthwashes are marketed to make it look like you are spitting out massive chunks of hidden plaque and "gunk" your toothbrush missed, it is largely a clever cosmetic chemistry trick. The vast majority of the clumps you see in the sink are just your own healthy saliva proteins reacting to the acid, rather than pure bacterial buildup. It is definitely visually satisfying, but you aren't actually pulling mountains of plaque off your teeth! The Science of the "Clump" The Main Actor (Citric Acid): Your saliva is full of naturally occurring proteins—specifically mucins—that keep your mouth lubricated and healthy. When you introduce a concentrated dose of citric acid, it rapidly lowers the pH level in your mouth. The Reaction (Coagulation): This sudden, highly acidic environment denatures (unfolds and breaks down) those salivary proteins. Once denatured, the proteins bind together and coagulate. The Result: Those coagulated proteins, mixed with microscopic dead skin cells and some loose oral debris, form the stringy, solid "clumps" you spit out. The Supporting Cast Sodium Phytate: This is a chelating agent, meaning it is engineered to bind to minerals like calcium (which is abundant in saliva and plaque). While its main job in this formula is to lift surface stains and prevent tartar from hardening, its binding action can contribute to the physical solidity of the clumps. PEG-40 Hydrogenated Castor Oil: This acts as an emulsifier and surfactant. It helps keep the water and the essential oils (like eucalyptus and thymol) mixed together, but it also helps sweep up the coagulated debris so it all washes out of your mouth in one go. Read more

A++++ 6 STARS

Ray PapazMarch 13, 2026✓ Verified purchase

Been using the Hismile iD whitening mouthwash and it actually makes my mouth feel super clean, like it’s pulling stuff off my teeth instead of just masking it. My teeth look a little brighter already and the fresh breath lasts way longer than I expected. A++++ Read more

The Ads Got Me… and I’m Glad They Did!

Rocio HernandezFebruary 27, 2026✓ Verified purchase

The ads definitely got me with all those “gunk removal” videos. I was curious and decided to give it a try. I did notice some gunk after my first use (not much after that), but what really impressed me is how fresh it keeps my breath ALL day. I’ve been using it twice daily, and I don’t even wake up with morning breath anymore. By far the most effective mouthwash I have ever used. I’ve already been recommending it to family and friends!

Another great Hismile product!!

Russell D. HarrisMarch 13, 2026✓ Verified purchase

Great product!! Works as described. Just make sure you follow the instructions and use regularly. A bit of a strong taste but nothing close to Listerine. Will definitely be buying this again. Read more
