MASHIRO flips the script on what a whitening toothpaste can look like. The compact, design-award-winning jar contains a green powder — not paste — which turns out to be the whole p oint. Powder can hold nearly double the cleaning agents of paste without getting too dense to use, so each brush genuinely does more. The micro-silica particles are sized at 10 microns or less, fine enough to lift staining without scratching the enamel underneath. It foams lightly, rinses clean, and does not leave that artificial mint-coated feeling that makes your post-brush coffee taste wrong. One jar lasts about 100 uses — two to three months of daily brushing — at a price that makes professional whitening sessions feel hard to justify. Show more
