The secret behind my white teeth? Mr.Fris.

After just one week, I could already see a difference in the photos I was taking. No sensitive teeth either.

I always had really yellow teeth and tried so many things, but then I came across Mr.Fris.

I drink coffee all day. Two weeks later, colleagues asked whether I'd been to the dentist.
Whitening goes shade by shade, not day by day. This is what happens from the first evening to the top-up two months later.
Tray in, leave it for 60 to 90 minutes, rinse. You'll see the first difference yourself in the photo, others won't yet.
The tipping point: now someone who sees you every day notices too.
After 5 or 10 trays, you've reached your result. How many shades that is depends on where you started.
One tray every 1 to 2 months keeps it in place. A set of 10 lasts well over a year.

4.8 / 5After a week I already saw a difference in the photos I was keeping. No sensitive teeth, and the fifteen minutes fit easily into my morning.
I drink coffee all day long, so I was sceptical. After two weeks I really see a difference in the before and after photos.
I have naturally sensitive teeth and never dared to whiten. Skipped one day when it started to twinge, after that it went fine.
From day five it started to show. Colleagues asked if I'd had something done to my teeth.
After years of red wine and cigarettes, I didn't have high expectations. The result is subtle but clearly visible.
Simpler than I thought. Gel in, tray on, rinse. No fuss with strips you constantly have to readjust.
I'd tried strips before, they always slipped. This tray just stays put and the result is much more even.
Knowing there's a dentist behind it gave me the confidence to try it. Great that it clearly states how long you can use it.
Started just in time for my sister's wedding. You notice it straight away in the photos, without it looking overly white.
The fifteen minutes are really doable. I do it while clearing my inbox, so I hardly ever forget.
The dentist quoted me over four hundred euros. This cost a fraction and I'm just as happy with it.
Did a second course as maintenance, six months after the first. The shade is fully back up to level.

Choose how many trays you want. Five lasts half a year, ten a whole year. Not happy? You'll get your money back within 30 days.
