Boots shoppers flock to buy £10 dentist-approved teeth whitening serum said to 'erase years of tea and coffee stains'

Shoppers are flocking to buy a Boots teeth whitening serum that is loved by dentists, and is said to help erase 'years' of tea, cofee, fizzy drink and smoking stains. The £10 teeth whitener has been flooded with rave reviews, with many saying their teeth have 'never been whiter'.

Usually costing £19, the Hismile V34 Colour Corrector Serum 30ml has been slashed to £10 for today (December 19) only, as part of Boots' weekly £10 Tuesday sale. The tooth serum works in a similar way to purple shampoo, where it uses colour theory to 'restore brightness' and neutralises any yellow tones on the tooth surface.

To use, brush your teeth like normal and then apply the serum with a soft bristle toothbrush or with a cotton swab and gently polish onto your teeth, specifically focusing on the areas that are the most yellow. It can be reapplied daily, and is recommended to use just before going out, to brighten your smile and boost your confidence.

The serum is described as being 'the perfect non-invasive brightening solution designed to conceal those pesky yellow stains that you just can't seem to keep away'. Unlike other teeth whitening products, it uses purple pigments to cancel out any yellow in your teeth (as they are opposites on the colour wheel), instead of using peroxide, which means this will be comfortable to use, even with sensitive chompers.

The Hismile V34 Colour Corrector Serum 30ml has racked up an impressive 4.5 stars out of five at Boots. Shoppers have been left impressed
