Beauty shoppers looking to brighten their smile can save up to 40% on a popular teeth whitening range from MySweetSmile, as the brand rolls out its Boxing Day discounts.
The award-winning collection includes powders, strips, pens and serums, with several products now priced under £20. Customers say they have “noticed a difference” after trying MySweetSmile’s products, particularly after seeing limited results with other brands.
The brand’s best-known item, the Teeth Whitening Powder, has been reduced from £29.99 to £17.99. Each pot offers a six-month supply, bringing the cost per use to around 48p. The formula contains calcium carbonate to polish teeth, pentasodium triphosphate to help break down stains, and strontium chloride hexahydrate, which forms a protective layer over enamel.
Alongside its original mint flavour, MySweetSmile has launched a new strawberry version with the same whitening ingredients and discount, aimed at customers who prefer a sweeter taste. The brand claims the powder takes just two minutes, twice a week, to gradually remove stains caused by coffee, tea, wine and tobacco.
Users are advised to dip a damp toothbrush into the powder and brush as part of their normal dental routine, alongside regular toothpaste.
For those who prefer whitening strips, the MySweetSmile Teeth Whitening Strips are also reduced to £17.99 from £29.99. Each pack contains 21 treatments using PAP (phthalimidoperoxycaproic acid), which is marketed as enamel-safe and gentle on sensitive teeth. Designed for daytime wear, the non-slip strips are worn for 30 minutes, with a recommended seven-day course for best results.
Shoppers spending £30 or more during the Boxing Day promotion can also receive a free box of whitening strips.
Targeted whitening is offered through the Precision Teeth Whitening Pen, now £14.99, down from £24.99. Using the same PAP formula, the pen is designed for hard-to-reach areas. Users twist the base to apply gel directly to stains, leave it on for 10 minutes, then rinse. Each pen provides up to 30 applications.
The sale also includes products focused on gum and enamel health. The Hyaluronic Gum Serum has been reduced to £17.99 from £29.99. It contains hyaluronic acid, which the brand says helps reduce inflammation, support gum repair and combat bad breath. Customers are advised to apply it to the tongue, spread across the gums and rinse after two minutes.
Similarly priced is the Enamel Care Serum, also £17.99, designed for people with sensitive teeth. It uses hydroxyapatite, a key component of tooth enamel, to help strengthen enamel and reduce sensitivity when used daily.
While MySweetSmile has been named “Best Teeth Whitening Brand” by The Independent for two consecutive years, alternative products are also attracting attention. Smile Therapy’s PAP+ Pro Teeth Whitening Powder is currently £19.99, reduced from £39.99, and holds an average rating of 4.8 out of five. Boots is selling the Polished London Professional Teeth Whitening Kit with PAP Pro technology for £49.99, which includes a light-activated treatment.
Customer feedback on MySweetSmile products has been mixed but largely positive. One shopper said tooth discomfort disappeared and their teeth looked “cleaner and whiter,” while another noticed gradual improvement after nearly two weeks of use. Some users, however, reported limited whitening results or minor issues with product application.
Despite varied experiences, the discounted range has proven popular, with many shoppers taking advantage of the Boxing Day offers to try multiple teeth whitening products at a lower price.
