Curaprox’s “Black Is White” is a black toothpaste that doesn’t contain chemical bleaching agents, as most whitening pastes do. It contains activated carbon, absorbing the particles that cause discoloration and a physical blue filter that makes the teeth even whiter. Black Is White protects the enamel with a thin film thanks to the hydroxylapatite, and even fills in small holes. It also has a slightly cooling effect!
No SLS. No triclosan. No bleaching agents. Made in Switzerland.
