According to research, a bright, white smile is an indicator of good health, youth and even success.

But, if you’re a tea drinker, red wine lover or coffee addict, you’ll probably know the struggle of staining. 

No matter how committed you are to brushing twice a day, modern life has a habit of clinging to your enamel.

Thankfully, we’ve got just the thing to keep your grin gleaming – and it’s currently on offer for Black Friday.

Teeth whitening specialist MySweetSmile has just rolled out its biggest-ever Black Friday event, and rather than a blink-and-you-miss-it day of discounts, it’s gone all in with 11 days of unmissable offers and daily treats running from 21 November right through to 1 December.

The brand has brought back the two offers shoppers wait all year for: you can buy two products and get a third completely free, or buy one product and pick up a second item for half price.

Ideal if you’re stocking up before party season or treating someone else to a brighter smile, these offers make snapping up pearly white essentials more affordable than ever.

You can shop the event across Amazon and TikTok Shop, but the real fun is happening on the brand’s own site, where shoppers who spend over £30 can snag a new full-size free gift every single day.

Essentially it’s a smile-themed advent calendar for anyone hoping to look a little fresher before the festive season kicks into full swing.

There’s also a hefty 40% off site-wide, bringing MySweetSmile’s bestselling, enamel-safe and peroxide-free Teeth Whitening Powder that users say ‘actually works’ from £29.99 down to only £17.90.

Designed specifically for those with sensitive teeth and better enamel care in mind, the MySweetSmile Teeth Whitening Powder is an affordable and pain-free solution to dull, stained teeth.

Designed to be used every day after brushing your teeth, the non-abrasive formula instantly gets to work on deep-set stains from coffee, tea, wine and more while ensuring zero pain or sensitivity thanks to its peroxide-free formula, leaving teeth ‘noticeably whiter’ and gleaming.

It’s pretty clear that with daily freebies, generous savings and clever bundle deals, MySweetSmile’s Black Friday event is less about frantic shopping and more about treating yourself. 

Check in each day to see what the freebie is, stock up on favourites, and by the end of the 11 days you’ll have a noticeably brighter smile and a few extra goodies for the festive season.

In the mean time, explore our top picks from the MySweetSmile Black Friday 2025 sale below.
