The powder, available in mint and strawberry varieties, is designed to lift yellowing caused by ageing, tea, coffee, smoking, wine and more.

How to use the powder
Users should dip a damp toothbrush into the product, add their usual toothpaste on top, and brush for two minutes. This should be repeated daily for 14 days, then twice per week thereafter to maintain results.

Shopper reviews
Amazon reviews are generally positive. One user said: "I use this twice a day since I last went to hygienist and my teeth are looking great and I'm 70!" Another wrote: "Really impressed, I've bought more than once. Leaving your mouth with a refreshing glow. A few shades whiter."
One customer shared: "Black coffee & smoking had totally ruined my teeth, to the point I avoided smiling in photos. A friend of mine recommended I use this powder, and omg after a few weeks the difference is incredible. It's removed all the yellow stains and my teeth are looking 10x better."
Another added: "I love looking at my teeth now and I've only used three times! My teeth were stained from all the tea I drink and I use to smoke, hadn't whitened since."
One reviewer gave four stars, noting: "Not sure any colour change but teeth feel clean." Others reported seeing results within days, with one saying: "In day 3 I saw the results. It does what it says in the package."
The product is available now in MySweetSmile's sale.
