From The UK's #1 Highest-Rated Whitening Brand
You might know us for our award-winning Teeth Whitening Powder — trusted by over 1,000,000 customers and rated Excellent on Trustpilot.
These are the new & improved premium strips from the same UK brand. Same Dermatest® clinical validation. Same dentist approval. Same peroxide-free, sensitivity-free formula.
About half the people who find us nearly don't buy because it sounds too good to be true. Once they try it, the most common thing we hear is "I wish I'd found this sooner."
"I'd been using whitening toothpaste for years, and my teeth just kept getting more yellow. I thought that was it — you get a little older, and your teeth go with it. These strips changed my mind. One week in, and my husband asked what I'd done differently. I actually smile properly in photos now."
– Laura, 38 🇬🇧
"Years of black coffee had done a number on my teeth. I'd stopped smiling in photos because I hated how they looked. My daughter ordered these for me, and I didn't expect much, but the stains started lifting after the first treatment. No sensitivity either, which is what put me off strips in the past."
– Tom, 45 🇮🇪
"I'd tried so many whitening products — strips that hurt, an LED kit that did nothing, even a £300 dentist appointment that faded within months. These were different. 30 minutes a day for a week, and my teeth haven't looked this bright in years. Even my dentist noticed."
– Rachel, 34 🇺🇸
Premium Whitening Strips — Engineered Differently
Most whitening strips don't deliver what they promise.
Purple 'colour-correcting' strips use an optical effect that washes off the moment you eat or drink. Nothing actually changes.
American discount strips use hydrogen peroxide. They bleach, but they also burn your gums and weaken your enamel.
These strips are different. The Advanced PAP Formula is peroxide-free, so it lifts years of stains without the burn. Clinically-proven by Dermatest®, designed by UK dentists, trusted by over 1,000,000 customers.
Awarded 'Best Teeth Whitening Brand' 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 won Best Teeth Whitening Product in both 2023 and 2024. No other whitening product has won it twice.

How It Works & Why It Keeps Working
Lifts Years of Deep-Set Stains
Coffee, tea, red wine, tobacco, curry, and natural ageing all leave porous surface stains that sink deeper into your enamel the longer they sit. Our Advanced PAP Formula penetrates deep into the enamel and breaks down stain molecules through gentle oxidation — no bleaching, no enamel damage.
Whitens Without The Sensitivity Other Products Cause
Most whitening strips use peroxide to bleach, which is why they cause the burning sensitivity most customers remember. Our formula contains zero peroxide. The PAP actively oxidises stains without irritating gums or nerve endings. Clinically tested for enamel safety by Dermatest® in Germany.
A Routine That Maintains Your Results — Not A One-Off Fix
Professional dental whitening costs £300+ and starts fading the moment you walk out. These strips are designed for a 3-month routine: a 7-day cycle to lift years of stains, followed by 1-2 treatments per week to keep your smile consistently bright.
What Makes These Strips Different
✔ Advanced PAP Formula – Premium peroxide-free whitening active. Lifts deep-set stains without bleaching.
✔ Whiter teeth in 7 days – Visible results from the first treatment, full transformation after a 7-day cycle.
✔ Zero sensitivity – MySweetSmile is clinically-proven by Dermatest® in Germany.
✔ A complete 3-month routine – 21 treatments per box. £1.90 per treatment, around £13 per month of premium whitening.
✔ 30 minutes, fits your routine – No trays, no LED, no mess. Apply while getting ready, working, or relaxing.
✔ From the UK's #1 highest-rated whitening brand – Created by the team behind MySweetSmile's award-winning Powder.
What Is PAP — And How Does It Work?
PAP is the active ingredient that does the whitening work in our strips — a peroxide-free alternative to the bleaching agents used in most discount strips.
Peroxide bleaches teeth by penetrating the enamel itself. It works, but it weakens enamel structure and causes the burning sensitivity most customers remember.
PAP works through gentle oxidation. It lifts stains at the surface of the enamel without penetrating the structure. Same visible result — without the sensitivity, gum irritation, or enamel damage.
Got Questions? We've Got Answers
Each box contains 21 treatments. Open a sachet, peel the strips, and apply the smaller one to your bottom teeth and the larger to your top. Leave them on for 30 minutes, then peel off and rinse.
For the full routine: use daily for 7 days to lift years of stains, then 1-2 strips per week to maintain. One box gives you a complete 3-month whitening routine.
Nearly half of our customers said the same thing before they bought.
The difference is in the formula. Most discount strips use hydrogen peroxide, which bleaches teeth — but also burns gums and weakens enamel. Our strips use an Advanced PAP Formula, which oxidises stains without bleaching. Premium results without the peroxide burn.
No. Most whitening products cause sensitivity because they use peroxide to bleach the enamel. Our formula contains zero peroxide.
The Advanced PAP Formula works through oxidation rather than bleaching, so it lifts stains without irritating gums or nerve endings — Clinically-proven as sensitivity-free by Dermatest® in Germany.
Yes, and older teeth are actually where the strips tend to deliver the most visible results.
As you age, your enamel naturally thins and absorbs more staining over the decades. That yellowing looks permanent, but it isn't — the Advanced PAP Formula penetrates deep enough to lift it without being abrasive.
About 14% of our customers almost didn't buy because they assumed it wouldn't work at their age. It does.
Most customers see a visible difference after their first treatment. The full transformation comes after a 7-day cycle of daily use.
After the initial 7 days, complete 1-2 treatments per week to maintain your results.
Our whitening strips use a scientifically backed formula that’s peroxide-free, enamel-safe, and designed to deliver professional-level whitening without irritation:
- PAP (Phthalimidoperoxycaproic Acid) – A powerful yet gentle whitening agent that safely removes all types of stains and discolouration without damaging enamel.
- Sodium Hydroxide – Helps break down deep-set stains and brighten enamel.
- PVP (Polyvinylpyrrolidone) – Forms a protective barrier to prevent future stains, keeping your teeth whiter for longer.
Full EU Ingredients List: Glycerin, PVP, Ethylcellulose, Phthalimidoperoxycaproic Acid (PAP), Hydrated Silica, Dicalcium Phosphate, Disodium EDTA, Sodium Hydroxide, Menthol, Cocos Nucifera Oil.
Yes, the strips are completely safe for all dental work. The formula won't change the colour of artificial teeth, but by keeping your surrounding natural teeth bright, your smile looks consistent and even overall.
If you have composite bonding, we recommend consulting your dentist before use.
A complete 3-month whitening routine. The first 7 days use 7 treatments daily for the initial cycle.
After that, 1-2 sessions per week are enough to maintain your results, using the remaining 14 treatments.
Three things do the work:
Phthalimidoperoxycaproic Acid (PAP) — the whitening active. Penetrates enamel and oxidises stain molecules without peroxide.
PVP (Polyvinylpyrrolidone) — the protective barrier. Forms a film over teeth that prevents new stains from settling.
Hydrated Silica + Dicalcium Phosphate — the gentle polish. Removes surface buildup that PAP doesn't reach.
Full ingredient list: Glycerin, PVP, Ethylcellulose, Phthalimidoperoxycaproic Acid (PAP), Alcohol, Hydrated Silica, Dicalcium Phosphate, Disodium EDTA, Sodium Hydroxide, Menthol.
No, avoid food and drink while the strips are on — it interferes with the whitening process.
After removing, rinse your mouth thoroughly. For best results, avoid staining foods and drinks for at least one hour after use.
The results are long-lasting, but daily coffee, tea, or red wine will gradually cause new stains over time.
That's why the strips are designed as a 3-month routine, not a one-off treatment. Following your initial 7-day cycle, 1-2 treatments per week maintenance keeps your results from fading.
The strips on their own are enough for most people — a 7-day cycle, then 1-2 treatments per week.
If you want maximum impact, our Pro Teeth Whitening Kit combines these strips with our award-winning Teeth Whitening Powder.
We recommend the strips for ages 18 and older.
