I immediately tracked the stuff down: It's called Email Diamant Rouge, it's French, and apparently, it's been around since 1893. Guess teeth whitening isn't such a modern phenomenon. Upon brushing with it for a week, I can also tell you the following: It's dark red, has an intense clove/licorice/mint taste, and gives the most immediate brightening effect I've ever witnessed from a toothpaste. Supposedly the secret is that it coats your teeth with natural light-reflective particles, making them sparkly yet somehow not red, while staining your gums--and, unfortunately, your tongue and your toothbrush--pinker so your teeth seem crisper-white in contrast. (I'd post a photo, but I'm reluctant to have a huge photo of my teeth on the Internet.) The drawbacks? It's expensive and messy, turning everything in its path hot pink. Watching the neon water swirl down the drain is kind of fun, though.
Am I the only one who'd never heard of this stuff? Do any of you use it?Read More »from E-mail Diamant Rouge Toothpaste: A strange-yet-effective teeth whitener
