I can only put the toothpaste every warmly! I know what it's like when you yellowish teeth - whether it has by cigarettes or coffee and many toothpastes promise that they make your teeth super mega white and nothing happens! What remains a there left? Bleaching, - Noo! I have had yellowish teeth themselves and have to say that my teeth are really become dramatically whiter already after 5 days by the Blend-a-med 3D White Luxe Brilliant shine and although I occasionally drink n Käffchen times and every day verqualme several Kippchen! So top toothpaste! Can I really only recommend it!
