Do whitening toothpastes work?: Mohinder Sira, Dental Hygienist
No toothpaste actually changes the colour of your teeth.
What whitening toothpastes do have, they have ingredients that can help remove or lighten surface staining, again, staining from tea, coffee, tobacco - it'll minimize the staining and if that is removed, it makes your teeth look brighter and cleaner, but doesn't change the shade, of your teeth. You would be looking at tooth whitening for that.
