It contains a refreshing mint and comes in white powder form. To use, simply brush it across your teeth for four minutes with your tooth brush - shoppers swear that it works on everyday stains from things like tea, coffee, red wine or smoking.

In the reviews, one shopper said: "I couldn't believe the difference after my first treatment! The reduction in stains and plaque between the two pictures is just amazing, my teeth look way whiter and they don't feel sensitive or rough whatsoever. I've recommended this to all my friends and family, thank you."

A second review read: "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!"

A third said: "On my second pot now. Just can’t believe how well on my stained 66 year old teeth. I didn’t want to smile at all because of staining from smoking and tea drinking. No cleaning at dentist for a few years has not helped. Within the first few days of using the powder the staining was going. Really happy with this product and will continue to use.
