How it works +

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.

Our origin story +

Japanese-inspired. Reimagined for the Western world.

We took inspiration from Japan’s popular propolis-based rinses – a post-brushing swish loved for lifting the residue a toothbrush misses and revealing it right in the sink. That idea became our starting point, not our finish line. To make our formula 100% vegan, we removed the propolis and developed our own elevated blend instead, combining essential oil components for freshness, with hydrogen peroxide for whitening maintenance. The result? iD Stain Whitening Mouthwash – inspired by Japanese oral care, reimagined to target and reveal the gunk brushing leaves behind while helping maintain your white smile.
