People with years of tea, coffee and fizzy drinks stains, as well as yellow teeth, are raving over a teeth whitening treatment, which, they claim, doesn't cause any teeth sensitivity and shows a difference within days.

The bestselling teeth whitening strips use a formula which is scientifically proven to whiten teeth, while being gentle on the most sensitive of mouths.

HeySmile's Whitening Strips currently cost £29.99 for 28 strips - which equates to 14 sessions, or two weeks' worth if you're using them daily.

However, for a limited time, they have been reduced to a more budget-friendly price of £19.99 - saving of £10. Each set comes with 28 strips, with the strips coming in sachets with sets of two inside making them more travel friendly.
