No. Purple toothpaste does not whiten your teeth. It leaves a tint on the surface that makes yellow look less yellow, so your teeth appear whiter for a short time. Nothing about the tooth has changed, and the effect wears off. To change the actual shade of your teeth, you need a whitening gel with a bleaching agent.

Full transcript of the video answer on whether purple toothpaste actually makes your teeth whiter, given by Amber-Lee, IRDH, at Bright White Dental Hygiene Clinic in Riverview, NB, serving Moncton and Dieppe.
Question: Does Purple Toothpaste Actually Make Your Teeth Whiter?
“No, purple toothpaste does not make your teeth any whiter. What happens is when you use that toothpaste, it's a dark colour, and it leaves like a dark image so that the rest of your teeth appear whiter. So those types of toothpaste don't actually whiten your teeth.”
Purple and yellow sit opposite each other on the colour wheel, so a purple tint cancels out some of the yellow you see. Hairdressers use purple shampoo on blonde hair for the same reason. It is a trick of colour. The product sits on the surface, and it comes off as you eat, drink and brush.
Independent research on purple toothpaste itself is thin. Colgate's own announcement for its purple toothpaste describes the effect as temporary. There is no bleaching agent doing the work, so there is no lasting change to expect.
As an occasional colour boost before a photo, it is unlikely to do much harm. Check two things. If it is a serum or a paste without fluoride, it should not replace your regular toothpaste. If a product feels gritty, leave it, because abrasive pastes wear down enamel and can make teeth look more yellow over time.
A cleaning and polish takes off surface stain. To change the shade, Bright White offers in-chair whitening for $350 plus tax or custom take-home trays for $300 plus tax. Whitening takes teeth to their own natural white, and Amber-Lee will tell you what to expect before you spend anything.
