What is a Purple Whitening / Colour-Corrector Toothpaste
“Purple whitening toothpaste” doesn’t usually mean it bleaches your teeth like professional whitening. Instead, it uses purplish / violet dyes / pigments to cancel out or mask yellow tones in your teeth. The principle is colour theory: purple is opposite yellow; when purple pigment lands over yellowish enamel, it can make the tooth look whiter/less yellow.
Some of them also include mild abrasives or “micro-polishing crystals” to remove surface stains, plus fluoride for regular oral health. But many do not have strong bleaching agents like hydrogen peroxide or carbamide
