    Seeing what was left behind even after brushing was crazy! It clumps up all the plaque so you can literally see it in the sink. My mouth has never felt this deeply clean.

    Finally, a mouthwash that doesn't burn my whole mouth! I started using this right before my whitening strips, and my teeth are definitely looking brighter. Tastes super fresh too.

    I am honestly obsessed with this stuff. It's oddly satisfying to see the gunk wash away every morning. It leaves my breath fresh for hours without any harsh chemical aftertaste. A must-have!

    Step 1: Swish
    Pour about a capful (15-20ml) of MIYO. Swish vigorously for 30 to 60 seconds. This allows our alcohol-free iD formula to find and bind to the hidden plaque. Do not swallow.

    Step 2: Spit & Reveal
    Spit the mouthwash into the sink. You will immediately see the hidden dirt, plaque, and buildup that your toothbrush missed, now temporarily highlighted.

    Step 3: Brush Away & Shine
    Gently brush the highlighted areas with your toothbrush to easily remove the stubborn gunk. Rinse your mouth with water and enjoy a flawlessly bright, dentist-clean smile!

    MIYO iD Stain is not your average mouthwash.

    This oral rinse works with your routine to help maintain white teeth, freshen breath, and lift build-up from the areas brushing can miss. As you rinse, the formula interacts with oral debris, pulling them into visible particles you can actually see in the sink. That’s what your toothbrush didn’t catch.

    Use as directed as part of your daily oral care routine. Visible residue is not guaranteed and depends on individual factors. Results may vary between individuals.

    Perfect for your daily oral care routine at home. Use it every morning to kickstart your day with a deep cleanse, or at night to wash away the day's buildup. It is the ultimate prep step to use right before brushing your teeth or applying teeth whitening strips and gels to maximize their effectiveness.

        It's incredibly easy! Simply pour a small amount into the provided cup, swish it vigorously around your mouth for 30 to 60 seconds, and spit it out. Proceed to brush your teeth with your regular toothpaste immediately after.

        Absolutely. Our formula is designed to be tough on stubborn daily stains but exceptionally gentle on your enamel. It contains no harsh abrasives, making it completely safe and pain-free for those with sensitive teeth or gums.

        For maximum stain-removing results, we recommend using it once daily. Most of our customers prefer incorporating it into their morning routine to break down coffee or tea stains before brushing.

        No, it does not. Think of it as a pre-treatment for your smile. The mouthwash works to loosen and break down daily buildup and surface stains, allowing your regular toothpaste to clean your teeth much more effectively.

        When used once daily as directed, a single bottle is perfectly sized to last you approximately 30 days, making it an easy addition to your monthly personal care routine.

        • Strange but very good 🤣

          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 than usual. Strange but very good hahaha

        • I recommend it!!!

          It’s not hype! If you’re ready for a new dental journey bucks up, grab a little cup , pour up a little and get set to see the results. This mouthwash pulls the gunk AND loosens the plague around your teeth as well. So it’s most definitely NOT a lie or over hyped your breath will be beyond fresh for hours and no morning breath. I recommend it.

          Emily A.

        • I lovee itt bro!

          Woaw! Just gave it a try . The flavor is definitely intense & unexpected. A bunch of gunk that was floating around inside of the mouthwash that I wasn’t expecting Did leave my mouth feeling more clean longer ... Definitely would recommend to people who are looking for alternatives to traditional whitening mouthwash!

        • Game Changer

          I’ve always struggled with stubborn coffee stains on my teeth, but adding this mouthwash to my routine completely changed the game. It instantly targets the stains and leaves my mouth feeling incredibly fresh. I haven't had a dull smile since.

        • I recommend it

          Having super sensitive teeth means I'm usually terrified to try new stain-removing products, but this mouthwash is incredibly gentle. It brightens my smile without causing any pain or sensitivity at all.

          Skye L.

        • The results are incredible!

          I’ve incorporated this into my daily routine, and I use it every single morning without fail. I swish it around right before brushing to help break down the daily buildup and yellowing that regular brushing misses. The results are incredible!
