"I always recommend completing at least two full cycles. PAP needs consistent use to fully oxidise deep-set stains — one month gets you there, two months keep you there."

🟣 How It Works
+
Step 1 — Peel
Remove the strip from the packaging and separate the upper from the lower.
Step 2 — Apply
Press firmly onto clean, dry teeth. The strip moulds to your smile for full coverage.
Step 3 — Wait 30 minutes
Go about your day. The purple formula corrects yellow tones on contact while PAP works on surface stains underneath.
Step 4 — Remove & rinse
Peel off and rinse any residue. That's it.
Use once daily for 7 consecutive days. Repeat monthly for maintenance.
✨ What's Inside
+
Every One Smile strip combines six premium ingredients:
PAP (Phthalimidoperoxycaproic Acid) — our active whitening agent. Oxidises surface stain compounds without peroxide, without sensitivity.
Purple Colour-Correcting Formula — purple sits opposite yellow on the colour wheel. The moment the strip touches your teeth, yellow tones are visually neutralised.
Hydroxyapatite — a mineral naturally found in tooth enamel. Remineralises and protects your teeth while you whiten.
Potassium Citrate — actively reduces tooth sensitivity during and after treatment.
Coconut Oil — natural antibacterial properties for a deeper clean feeling.
Menthol — leaves your mouth feeling fresh and clean after every session.
🦷 Is It Safe for Sensitive Teeth?
+
Yes — and here's why.
Most whitening products use hydrogen peroxide, which penetrates the enamel and causes that familiar stinging sensation. One Smile uses PAP — a peroxide-free alternative that works on surface stains only, leaving the enamel untouched.
We also include Potassium Citrate (specifically added to reduce sensitivity) and Hydroxyapatite (which actively remineralises enamel during treatment). So instead of weakening your teeth while whitening, One Smile protects them at the same time.
If you have active cavities, crowns, veneers or are pregnant, we recommend checking with your dentist before use. For everyone else — you're good to go.
💰 Results or Your Money Back

"Honestly? I bought these expecting nothing. Tried so many whitening products before and none worked. But I figured worst case I'd just get a refund. First session and I could already see a difference. By day 7 I was obsessed. Never asked for that refund."
Amy Thompson,

"I can't even eat ice cream without my teeth hurting, so whitening strips always scared me. These have no peroxide though, and I felt absolutely nothing. No pain, no sensitivity. And somehow they actually work? My sister asked if I'd been to the dentist on day 5."
Sarah Lawson,

"I'm the worst with routines. But these are literally just stick and wait 30 minutes while you do your thing. I noticed a difference after the very first use, which I wasn't expecting at all. One week in and my friends started asking what I'd done."
Claire Bennett,

"Three coffees a day and red wine at dinner — you can imagine my teeth. Thought only a dentist could fix them at this point. By day 3 the stains I'd had for years were actually fading. Now I just use one strip a week to keep it up. Game changer."
Luke Davies,

Verified Buyer
"I was about to book a professional whitening session — like, €300+ kind of thing. Saw these on TikTok and thought I'd try before spending that much. Glad I did. After one week my teeth looked better than my friend's who actually went to the dentist. Saved me a fortune honestly."

Your Question Answered
Is it safe for sensitive teeth?
+
Yes — and this is actually where One Smile stands out. Our formula uses PAP instead of hydrogen peroxide, which means it works on surface stains without penetrating the enamel. We also include Potassium Citrate, specifically added to reduce sensitivity during treatment, and Hydroxyapatite to remineralise and protect your enamel while you whiten. If you have active cavities or specific dental concerns, we always recommend checking with your dentist first.
How long do results last?
+
The PAP whitening results are long-lasting — how long depends on your habits. Coffee, wine, tea and smoking will gradually reintroduce surface stains over time. Most customers do a full 7-day cycle once a month to maintain their results. That's why our monthly maintenance pack exists.
Can I use it with crowns or veneers?
+
One Smile works on natural tooth enamel only. Crowns, veneers, bridges and other dental restorations won't change colour with whitening treatments of any kind — including ours. If you have significant dental work, we recommend consulting your dentist before starting any whitening routine.
How often should I use it?
+
Once daily for 7 consecutive days for the initial cycle. After that, one session per week is enough to maintain your results. If you're a heavy coffee drinker or smoker, you may want to repeat the full cycle once a month.
When will I see results?
+
Most customers notice a visible difference after the very first session — that's the purple colour correction working immediately. Significant whitening from the PAP formula typically shows within 3 to 5 days of consistent use. Full results after the complete 7-day cycle.
What if it doesn't work for me?
+
We offer a full 30-day money-back guarantee — no conditions, no small print, no questions asked. If you complete the cycle and aren't happy with your results, contact us at hello@onesmile.com and we'll refund you in full. Simple as that.
