Go Black!
Natural whitening with the new Black is White series by Curaprox.
Just like the "Black is White" toothbrushes: they offer a whole new cleaning experience. They're gentle on teeth and gums—thanks to Curen® floss with whitening activated carbon particles—but ruthlessly tough on plaque.
Black is white toothpaste restores tooth discoloration with the leading whitening agent: ACTIVATED CARBON. Activated carbon gives the toothpaste its black color and your smile its sparkling white. Without corrosive, bleaching substances. "Black is white" toothpaste promotes oral health with enzymes that support the protective function of saliva and hydroxyapatite - an ingredient that strengthens tooth enamel. It contains a blue filter that gives even whiter teeth. Without bleach, corrosive substances, SLS & triclosan. It can be used as a daily toothpaste without restrictions. With a cool lemon flavor!
