Clinically Tested & Dentist-Approved
Tested in Germany by Dermatest® and awarded their 5-Star Seal of Approval. 95% of clinical trial participants reported zero sensitivity, and in an October 2024 study, 65% of users saw visible results within 14 days. 35% noticed a difference in the first 7 days.
This isn’t a whitening toothpaste that promises results on the box and delivers nothing in the mirror. It’s a dentist-approved formula that’s specifically designed to lift the stains your toothpaste leaves behind.
Over 1,000,000 Customers Stopped Hiding Their Smiles
About half the people who find us nearly don’t buy because it sounds too good to be true. But once they try it, they keep coming back — and the most common thing we hear is “I wish I’d found this sooner.”
Over 1,000,000 customers have used this powder to lift years of coffee, tea, and tobacco stains. Not with harsh chemicals or expensive dental appointments — just 2 minutes added to the routine they already have. Whether you’re 25 or 65, it works the same way.

“I’d been using supermarket whitening toothpaste for years, and my teeth just kept getting more yellow. I thought that was it — you get older, and your teeth go with it. This powder changed my mind. Two weeks in, and my daughter asked what I’d done differently. I actually smile properly in photos now.”
– Margaret, 63 🇬🇧
“Years of black coffee had done a number on my teeth. I’d stopped smiling in photos because I hated how they looked. My wife ordered this for me and I didn’t expect much, but the stains started lifting after the first few uses. No sensitivity either, which is what put me off strips.”
– James, 45 🇮🇪
“I was sceptical — I’d tried whitening toothpaste, strips, even an LED kit. Nothing worked without making my teeth ache. This was different. Two minutes in the morning before my normal toothpaste, and I could see a difference within a week. Even my dentist noticed.”
– Emily, 39 🇺🇸
Your Toothpaste Cleans. This Powder Whitens
56.7% of our customers were using whitening toothpaste before they found us. Most had been using it for years. The problem is that toothpaste is designed for hygiene, cavity protection, gum health, and fresh breath. It’s not designed to lift stains, which is why your teeth can still look the same no matter how often you brush.
This powder does what toothpaste can’t. It lifts surface stains from coffee, tea, wine, smoking, and natural ageing — without sensitivity, without peroxide, and without replacing your existing routine. You brush with the powder first, then follow up with your regular toothpaste as normal.
Awarded 'Best Teeth Whitening Product' Two Years Running
The Independent’s IndyBest awards are one of the UK’s most trusted product reviews, tested and judged by an independent editorial panel. MySweetSmile Powder won Best Teeth Whitening Product in both 2023 and 2024, and no other whitening product has won it twice.
Also featured in The Guardian, The Times, and the Daily Mail. Rated “Excellent” on Trustpilot — 7,500+ reviews at 4.4 out of 5.
Lifts Stains That Build Up Over Time
Coffee, tea, red wine, tobacco, curry, and natural ageing all leave porous surface stains that get deeper the longer they sit. The formula uses Calcium Carbonate to gently polish them away and Pentasodium Triphosphate to break down discolouration and stop new stains from forming. It’s non-abrasive, so it cleans without scratching or stripping your enamel.
Whitens Without The Sensitivity Other Products Cause
1 in 5 people associate teeth whitening with pain, damage, or harsh chemicals. This formula contains Strontium Chloride, which forms a protective barrier over the nerve endings in your teeth so you get the whitening without the sting. There’s no peroxide, no bleach, no parabens, and no PEGs, and it’s safe for sensitive teeth and thinning enamel.
A Routine That Maintains Your Results — Not A One-Off Fix
Professional whitening costs £300+ and the results start fading as soon as you walk out. LED kits tend to overpromise and underdeliver. This powder is designed to be used consistently — daily for the first 14 days to lift built-up stains, then twice a week to stop them coming back. One tub lasts up to 6 months.
What Makes This Powder Different
✔ Whitens where toothpaste can’t – Your toothpaste maintains hygiene. This powder lifts the surface stains it leaves behind.
✔ Whiter teeth in 14 days – In a clinical study, 65% of users saw visible results within two weeks, and 35% noticed a difference in the first 7 days.
✔ Zero sensitivity – 95% of Dermatest® clinical trial participants reported none. No peroxide, no harsh chemicals, and safe for ageing enamel.
✔ 2 minutes, twice a week – You add it before your normal toothpaste. No trays, no strips, no mess.
✔ One tub lasts up to 6 months – That works out at roughly 32p per use, which is less than a single coffee.
Got Questions? We've Got Answers
Dampen your toothbrush, dip it into the powder, and brush for 2 minutes. Rinse your mouth, then brush with your regular toothpaste to remove debris.
For the first 14 days, use it every day — that’s when the built-up stains start lifting. After that, twice a week is enough to maintain your results.
No, they do two different things. Your toothpaste handles the daily hygiene — cavities, gum health, and fresh breath. The powder is specifically for lifting stains. You use the powder first, then brush with your regular toothpaste straight after.
Nearly half of our customers said the same thing before they bought.
Dermatest® in Germany clinically tested the formula and awarded it their 5-star seal of approval. 95% of participants had zero sensitivity.
The Independent named it the best whitening product on the UK market in 2023, and again in 2024 — no other product has won that twice.
There are over 7,500 reviews on Trustpilot at 4.4 out of 5, and over 1,000,000 customers have used it.
Find out for yourself why it works.
No. Most whitening products cause sensitivity because they use peroxide to bleach the enamel, but this formula doesn’t contain any peroxide at all.
Instead, it contains Strontium Chloride, which forms a protective barrier over the nerve endings in your teeth. In the Dermatest® clinical trial, 95% of participants reported zero sensitivity — including people who already had sensitive teeth going in.
There’s no peroxide, no bleach, no parabens, and no PEGs.
If your teeth are generally quite sensitive to things like cold drinks or ice cream, we’d recommend pairing the powder with our Enamel Care Serum. It repairs and strengthens enamel overnight.
Yes, and older teeth are actually where it tends to work best.
As you age, your enamel naturally thins and absorbs more staining from everything you eat and drink over the years. That yellowing looks permanent, but it isn’t — it’s surface discolouration that has built up over time, and the powder lifts it without being abrasive. So you’re not stripping enamel you can’t get back.
About 14% of our customers said they nearly didn’t buy because they assumed it wouldn’t work at their age. It does.
If your enamel is on the thinner side, our Enamel Care Serum remineralises and strengthens it overnight.
In an October 2024 clinical study by Dermatest®, 35% of users saw a visible difference within 7 days, and 65% within 14 days.
We recommend using the powder daily for the first 14 days, as that’s when the accumulated staining starts shifting. After that, twice a week is enough to prevent new stains from settling back in.
It works on the stains that build up in the pores of your enamel over time — coffee and tea are the most common ones our customers mention, followed by smoking and vaping stains, red wine, berries, curry and sauces, and the general yellowing that comes with age.
The formula is non-abrasive, so unlike charcoal powders, it dissolves stains gently rather than scraping the surface of your teeth.
Both flavours use exactly the same formula and deliver the same results. The only difference is the taste. We added the Strawberry Powder because a lot of customers asked for a non-mint option, so it really just comes down to which flavour you prefer.
Yes, it’s completely safe for all dental work. The powder won’t change the colour of artificial teeth, but it keeps them clean and smooth. And by keeping your surrounding natural teeth bright, your smile looks consistent and even overall.
Each tub lasts about 6 months when you’re using it twice a week. The formula is concentrated so you don’t need much per use — it works out at roughly 32p each time.
There are three active ingredients, each doing a different job:
- Pentasodium Triphosphate breaks down and dissolves the stain molecules sitting in your enamel.
- Calcium Carbonate gently polishes plaque and surface debris off the teeth without scratching.
- Strontium Chloride coats the nerve endings to prevent any potential sensitivity while the powder works.
Full Ingredient List:
Mint: Calcium Carbonate, Pentasodium Triphosphate, Menthol, Sodium Lauryl Sulfate, Sodium Saccharin, Mentha Viridis Leaf Oil (Spearmint Oil), Allantoin, Strontium Chloride Hexahydrate, Limonene.
Strawberry: Calcium Carbonate, Pentasodium Triphosphate, Menthol, Sodium Saccharin, Fragaria Vesca (Strawberry) Fruit Extract, Mentha Viridis (Spearmint) Leaf Oil, Sodium Lauryl Sulfate, Beta Vulgaris (Beet) Root Powder, Carvone, Allantoin, Hydroxyapatite, Strontium Chloride, Limonene, Papain, Bromelain, Tocopheryl Acetate.
No, the powder is fluoride-free. It’s also free from peroxides, parabens, PEGs, and phthalates. You get your fluoride from your regular toothpaste, and the two are designed to work alongside each other without any overlap.
The powder on its own is enough for most people — daily for the first 14 days, then twice a week after that.
If you want to go further, our Pro Teeth Whitening Kit pairs the powder with our PAP Teeth Whitening Strips, which work beneath the enamel surface on the deeper yellowing that the powder can't reach on its own. The Kit also includes a Free Breath Spray.
We recommend it for ages 12 and older.

The powder lifts surface stains. But some discolouration sits beneath the enamel surface — years of coffee, tea, and ageing that the powder can’t reach. The strips can.
The MySweetSmile Pro Teeth Whitening Kit combines both:
The Teeth Whitening Powder — lifts surface stains and keeps them gone with your twice-weekly routine.
The PAP Teeth Whitening Strips — penetrate beneath the surface to reverse deep-set yellowing. Clinically backed 7-day results.
