A Whiter Smile In 3 Simple Steps

Step 1: Peel & Apply

Apply the longer strip to your top teeth and the shorter to your bottom. They're dry and non-slip, so they press on and stay put until you take them off.

Step 2: Leave For 30 Minutes

The strips get to work as soon as they're on. Cook, tidy up, do your make-up, or just relax on the sofa. You'll barely feel them while they whiten.

Step 3: Peel Off & Rinse

Peel the strips away and rinse off any residue. Your teeth get gradually whiter with every treatment, and after 14 days, your full result is complete.

What To Expect Using MySweetSmile Teeth Whitening Strips

DAY 1
DAY 7
DAY 14
DAY 1

A Brighter Smile From Day One

After your very first treatment, your teeth will look brighter and feel noticeably smoother, as Hydrated Silica gently polishes away the surface dullness that builds up day to day. The deeper whitening starts beneath the surface, and this is the first sign of it.

  • A subtle brightness you'll notice in the mirror
  • Teeth feel smooth, clean and refreshed
  • Zero sensitivity or irritation
DAY 7

Years Of Stains Begin To Lift

One week of daily treatments in, the transformation begins. The yellow tint starts visibly fading as the formula works deep within your enamel, lifting the stubborn stains from coffee, tea and wine that brushing alone was never going to shift.

  • The yellow visibly softening, tooth by tooth
  • Stains you thought were permanent, starting to lift
  • A difference you'll start to catch in the mirror
DAY 14

Reveal Your Whitest Smile Yet

Two weeks in, years of yellowing are gone. Whiter teeth every time you catch the mirror, and the confidence that comes with them: smiling freely in photos, laughing without a second thought, no more hiding your smile.

  • A visibly whiter smile that gets compliments
  • No more camera shyness in photos with friends & family
  • 7 bonus treatments left for special occasions or a quick boost

Over 1,000,000 People Stopped Hiding Their Smiles

"I'd used whitening toothpaste for years and my teeth just kept getting more yellow. I thought that was just getting older, but these strips proved me wrong. One week in, my husband asked what I'd changed. I actually smile in photos now."

– Laura, 38 🇬🇧

"Years of black coffee had done a number on my teeth, and I'd stopped smiling in photos altogether. My daughter ordered these for me, and I didn't expect much, but I could see the difference within the first week. No sensitivity either. Wish I'd found them sooner."

– Tom, 45 🇮🇪

"I'd tried everything, including a £300 dentist appointment that faded after just a few months. These were different. 30 minutes a day for two weeks, and my teeth haven't looked this bright in years. Even my dentist noticed!"

– Rachel, 34 🏴󠁧󠁢󠁳󠁣󠁴󠁿

Got Questions? We've Got Answers

Open a sachet, peel the strips, and apply the larger one to your top teeth and the smaller to your bottom. Leave them on for 30 minutes, then peel off and rinse. Use daily for 14 days for your full treatment.

Your 7 bonus treatments are for top-ups whenever your smile needs a boost, and most people start their next full treatment after 2-3 months.

42 strips, which is 21 complete treatments. That's your full 14-day whitening treatment, plus 7 bonus days free. You'll also find a cheek retractor for easy, even application, and a step-by-step instructions manual.

Nearly half of our customers said the same thing before they bought. The difference is what's actually in the strip.

Cheap peroxide strips bleach your teeth, but burn gums and weaken enamel while doing it. Most "gentle" peroxide-free strips have the opposite problem: their ingredients only polish the surface film, which is why the yellow never really shifts.

These use an Advanced PAP Formula, the one peroxide-free ingredient that works beneath the surface, oxidising the stains inside your enamel without bleaching. Real whitening, without the sensitivity.

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 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.

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.

Most people notice their teeth looking brighter after the first treatment. The yellow starts fading around day 7, and your full result lands at day 14.

Months, and every strip finishes with PVP, which seals your result behind a protective barrier that stops new stains settling. Daily coffee, tea or red wine will gradually build new stains over time, so use your bonus treatments for top-ups, and start your next full treatment whenever you're ready.

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, as 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.

We recommend the strips for ages 18 and older.
