Many home teeth whitening kits contain the same whitening agent used by dentists, but at much reduced concentrations (10% to 22%), a fact which often causes disappointment as the visible results we’re all after takes ages (and repeated treatments) to faintly emerge.

Now, though, you can get your teeth into a product which will lift your shade so noticeably you might need sunglasses to contemplate your smile in the mirror. White Shine Tooth Whitening Kit uses peroxide concentrations of 36%. Peroxide is the magic ingredient for tooth whitening, infiltrating the microscopic pores of the enamel and dentine and blitzing stains into smaller and smaller molecules, until they’ve effectively gone.

Whist deeply stained teeth may take as many as three weeks to lighten, the company guarantees that most people will see excellent results within 7 days of using the product. And, once whitened, the effects will last for up to three years. Currently on special offer for $30, this product normally retails at $90.
