A sceptic converted!
I bought the whitening kit as a prolific tea and diet coke drinker; my teeth have dulled over the years. I was sceptical as I have bought kits before but found them too faffy, so I never stuck with them. This kit is so much easier. You just paint the gel onto your teeth, pop the light in your mouth for 10 mins and you are good to go.
Amazing results
Having reached 70 a few weeks ago, I was pretty sceptical about the claims I was reading regarding this product. I am sceptical no more. After just 7 days my teeth are looking whiter than they have for years.
Great!
I bought a kit for my son and after only a few uses noticed a difference. I’m off to buy one for myself now. Easy to use with great results!
The basics
What is at-home teeth whitening?
Teeth whitening lightens the colour of your teeth and lifts stains from coffee, tea, red wine and food. At-home teeth whitening does it with a whitening gel you apply yourself, on your own schedule, instead of an appointment at the dental surgery.
How does it work?
Paint the peroxide-free PAP whitening gel onto your teeth with a SmilePro pen, then switch on the LED light with its built-in mouth tray for 10 minutes. The Advanced Teeth Whitening Kit gives up to 8 shades whiter in 7 days.
Do I need a light?
No. Teeth whitening strips are the light-free option, for up to 5 shades whiter. Each strip treatment takes 30 minutes.
Is it safe?
SmilePro whitening is enamel safe and sensitivity-free when used as directed. It is not for anyone under 18, pregnant or breastfeeding. If your teeth are sensitive or your gums are unhealthy, see your dentist first. More in Is teeth whitening safe?
How long does it last?
Whitening lifts stains, but new ones can form. After your first 7 days, a 10-minute top-up every 2 weeks keeps your smile bright (refills come in the Whitening Pen Pack). More in How long does teeth whitening last?

How long does each treatment take?
Each treatment is 10 minutes and the light switches off automatically. For best results, you can run up to three 10-minute cycles in one session, keeping the same gel on. Use the kit once a day for 7 days, then do a 10-minute top-up every 2 weeks.
Is it suitable for sensitive teeth?
The SmilePro formula is enamel safe and formulated to prevent sensitivity. If you already have sensitive teeth or other dental concerns, check with a dental professional before you start.
What's in the kit?
A rechargeable, water-resistant LED accelerator light, 3 whitening pens (30 treatments), a charging case (doubles as a travel case), a charging cable, a shade guide and an instruction guide.
How fast is delivery?
Orders to Sweden ship from our warehouse in the Netherlands. We aim to dispatch within 1 business day, and delivery takes 3 to 8 business days. Free tracked shipping on orders of 700 SEK or more.
What does the guarantee cover?
30 days to try the Advanced Kit, including the kit in the Ultimate Set. Not happy? Return it for a refund. Conditions apply.
More about teeth whitening
Teeth whitening at home or at the dentist?
There are two main ways to whiten your teeth: at the dental surgery, or at home with a teeth whitening kit. In-surgery whitening needs an appointment. At-home whitening fits around your day: with the SmilePro Advanced Teeth Whitening Kit it takes 10 minutes a day for 7 days, for up to 8 shades whiter.
A dentist is still the right first step if you have any concerns about your teeth or gums. To compare every SmilePro option, see our best at-home teeth whitening kits and products.
What's in the SmilePro teeth whitening kit?
- Peroxide-free PAP teeth whitening gel. It comes in 3 easy whitening pens, so you can paint it onto your teeth in seconds: 30 treatments in every kit.
- LED accelerator light. This teeth whitening device has a built-in mouth tray and blue and red LEDs, and switches itself off after 10 minutes. It is UKCA and CE marked.
- Charging case and cable. The case doubles as a travel case.
- Shade guide and instructions. Check your starting shade on day 1 so you can see the change on day 7.
After your 7-day course, refill pens from the Whitening Pen Pack keep your smile bright with a 10-minute top-up every 2 weeks.
Why choose SmilePro for teeth whitening?
- Enamel safe and sensitivity-free when used as directed.
- Fast. Up to 8 shades whiter in 7 days with the Advanced Kit, 10 minutes a day.
- Developed by dental professionals.
- 30-day money-back guarantee on the Advanced Kit (conditions apply).

How to keep your teeth white after whitening
- Do a 10-minute top-up every 2 weeks, or once a week if you drink a lot of coffee, tea or red wine.
- Rinse with water after coffee, tea or red wine.
- Brush twice a day with a whitening toothpaste to help lift everyday surface stains.
