The award-winning teeth whitening powder has been a best-seller on Amazon for two years running, and is currently cheaper than it’s ever been on global e-commerce site
I recently asked my dentist for a quote to get my teeth whitened, and at £300, I went home and immediately began looking for the best-recommended home solutions. MySweetSmile is a brand that came up time and again during my research, namely for its dentist-approved formulas and effective results – and now, it’s on offer.
As part of Amazon’s Spring Sale, which launched today (Tuesday, March 25), MySweetSmile is offering 30% off its award-winning teeth whitening and oral care range. The discount has been applied to a range of products, including gum serums, flavoured toothpastes and arguably their most popular product, the Teeth Whitening Powder.
MySweetSmile’s Teeth Whitening Powder has been Amazon’s number one best-selling product in the teeth whitening category for two years running, and has earned a stellar reputation with shoppers. It works to lift deep stains from coffee, tea, and wine using a peroxide-free, non-abrasive formula, and helps prevent new ones from forming so your smile stays brighter for longer.

It usually costs £24.99 for a tub, but as part of the sale, has been reduced to £17.49 . It’s the lowest price we’ve seen the product on Amazon, having previously been £18.74 around Christmas.
It’s earned a 3.8 star rating at the retailer, based on more than 5,000 reviews. One five-star comment read: “I use this and after 2 or 3 days I noticed my teeth getting brighter and whiter and that improved again to the point my partner asked if I’d had my teeth whitened . My teeth feel clean and smooth.”
Another added: “I was sceptical when first purchasing this product but safe to say after a month of daily use it really does work. I use the powder after I have cleaned my teeth with toothpaste and I am very pleased with the results. The initial taste of the powder took a little to get used to but with the results I’ve received with only one months use, I can deal with the bitterness. I’m excited to see more results.”
One user found it didn’t work quite as they’d hoped: “Found it really left teeth feeling very clean. Not sure if it actually whitened my teeth or not. I think it was worth a try.”
“As an avid coffee drinker, I had a noticeable stain on one of my teeth that made me quite self-conscious. I was even considering a visit to the dentist to have it removed. However, I saw this product on Instagram and decided to give it a try, hoping for the best,” wrote a fourth. “To my surprise, it completely removed the stain after just one use ! This product genuinely works, and I couldn’t be happier with the outcome. I plan to continue using it as recommended to maintain my teeth in great condition.”
There are plenty of other whitening powders available, too, including Dr Dent’s Crystal X Teeth Whitening Powder , which is currently available on Amazon for £12.95 for a six-month supply. Elsewhere, the Spotlight Oral Care Teeth Whitening PAP Powder was £30 but is currently £24 at Boots.
But the reason I was most drawn to MySweetSmile’s solutions wasn’t just the tempting price cut, but for the fact it’s backed by clinical testing and dentist approval. The brand has even earned the IndyBest award for Best Teeth Whitening Brand in both 2023 and 2024, and has over one million customers worldwide and an ‘Excellent’ rating on Trustpilot.
If you didn’t want to go for the powder, also included in the discount are the MySweetSmile’s PAP Teeth Whitening Strips , now £17.49, which provide fast, irritation-free whitening in ‘just seven days’, as well as the Precision Teeth Whitening Pen – a convenient solution for targeting stubborn stains on the go. Usually £19.99, it’s currently £13.99.
For those focused on overall oral health, MySweetSmile’s Enamel Care Serum and Hyaluronic Gum Serum offer advanced enamel strengthening and gum hydration benefits. The latter is designed to provide deep hydration, alleviate inflammation, and fortify gum tissue, aiding in the prevention and treatment of gum disease.
Meanwhile, the brand’s range of flavored toothpastes – including Fresh Mint , Strawberry , and Mango , available in both fluoride and fluoride-free options – work to strengthen enamel, fight plaque, and freshen breath. Another popular brand offering flavoured toothpaste is HiSmile, whose pastes, such as Mango Sorbet and Red Velvet, are currently half price at Boots, coming in at £4.50, compared to MySweetSmile’s £8.74 formula.
This Amazon discount is only available from March 25 to March 31 at 11:59pm, so for anyone looking to achieve a brighter smile or improve their oral hygiene routine without breaking the bank should consider that some of these products are the cheapest we’ve seen them.
