When it comes to hunting down oral care products, MySweetSmile has earned its stripes as Amazon’s best-selling whitening brand and was hailed as the Best Teeth Whitening Brand of 2023, 2024 and 2025 by the Independent. Now, whether you’re an oral hygiene enthusiast, have sensitive teeth, or simply wish to avoid shelling out a small fortune at the dentist, you can snag several deals from MySweetSmile this spring.

The sale, running from April 30th to May 5th, presents customers with a golden opportunity to snap up their bestseller – the Teeth Whitening Powder. This product, marked down from £24.99 to £17.49, has been clinically proven to banish stubborn stains on teeth and ward off new ones from forming.

To make the most of the powder, shoppers simply need to dip their brush into it, brush as per usual for two minutes, and rinse, reports Stoke on Trent Live. Also on offer are the Teeth Whitening Strips, which provide 21 daily treatments and pledge to eradicate deep-set stains and yellowing in just a week – all without the peroxide, irritation or sensitivity that other brands may sometimes induce.

These strips are reportedly backed by clinically proven Advanced PAP formulas that are straightforward to use and entirely non-slip. Users simply need to apply the strips for half an hour at a time to witness results.

The deal also includes the Enamel Care Serum, perfect for those with particularly sensitive teeth. The serum tackles the root cause of sensitivity by repairing and strengthening enamel while also preventing tooth decay and naturally enhancing whiteness.

Customers only need to apply the whitening powder to their toothbrush and brush for two minutes, similar to the brand’s Hyaluronic Gum Serum which targets gums. Whether it’s dry, inflamed or receding gums, these conditions can lead to issues if not addressed.

The serum, powered by high-concentration hyaluronic acid, is said to provide deep hydration, soothe inflammation and strengthen gum tissue to help alleviate symptoms of gum disease and prevent future problems. Gone are the days of tasteless and unsatisfying toothpastes as MySweetSmile offers a variety of flavoured toothpastes from strawberry to fresh mint, adding a little extra zest to your morning routine. They also provide both fluoride and fluoride-free options.

For those seeking alternatives to MySweetSmile, Smile Therapy is a viable option. This brand offers an array of products, including the convenient SmileTime Teeth Whitening Pen priced at £16.99 from Boots. Engineered for on-the-go use, the pen contains a non-peroxide solution to enhance and whiten teeth without causing irritation. Meanwhile, the PAP+ Pro Teeth Whitening Powder, Advance PAP+ Teeth Whitening Kit and electric toothbrushes comprise their product lineup.

Alternatively, the Colgate Max White Ultimate LED Whitening Kit, valued at £75 at Boots, encompasses one LED light, a storage container and whitening pen holding sufficient serum for up to 35 treatments. MySweetSmile has garnered widespread acclaim on Trustpilot, with an impressive 4.2-star rating based on 6,711 reviews. Clients have expressed their satisfaction, with one noting: “Really speedy delivery! Absolutely love this product – the results are amazing!”

One patron acknowledged the gum serum made flossing considerably less demanding, sharing: “The gum serum made flossing less of a chore. It definitely helped with the soreness I used to get.” Further, another client who experienced rapid outcomes shared: “I used the powder every other morning and noticed my smile looked cleaner after the first week.”

Another happy customer said about the strips: “It does what it says! Whiter teeth in 7 days for a wedding.” Additionally, one client credited the gum serum with making flossing easier, writing: “The gum serum made it easier to floss. I no longer got sore gums afterwards.”

Also, another happy customer praised the product’s ability to deliver results, saying: “I saw results after just one use, and my smile looked whiter in just a week!” While many customers were happy with their purchases, there were a few who questioned the product’s capabilities. A reviewer commented after three weeks of use: “Purchased this whitening powder as my teeth could do with a good polish. Been using it about 3 weeks now and I must say my teeth look cleaner but not whiter. I use it morning and night and then use my normal toothpaste, but I’m not convinced it’s whitening them any more than my toothpaste does.”

On the flip side, a different customer celebrated the powder’s effectiveness against tea blemishes, stating: “Got the powder to use with my regular toothpaste and it has made a huge difference with tea stains.” Make sure to mark your calendars – this MySweetSmile deal is set to take place from April 30th to May 5th.
