The timeline

What can you expect?

Whitening is by shade, not by day. Here's what happens from the first evening to your refresh in two months.

Treatment 1: The first shade

Put on the tray, leave for 60 to 90 minutes, rinse. You'll see the first difference in your photos, others won't yet.

Treatments 2 and 3: Others will see it

The turning point: now someone you see every day will notice too.

Treatment 4 and beyond: Until you're satisfied

You continue until your shade is exactly where you want it.

After that: Maintenance

One tray every 2 to 3 months keeps it in place. A set of 10 lasts well over a year.

After a week, I already saw a difference in the photos I took. No sensitive teeth, and the fifteen minutes easily fit into my morning routine.

Joost37 · verified purchase

I drink coffee all day, so I was skeptical. After two weeks, I really see a difference in the before and after photos.

Ahmed45 · verified purchase

I naturally have sensitive teeth and never dared to whiten. I skipped one day when it started to feel sensitive, but after that, it was fine.

Youssef28 · verified purchase

It started to become noticeable from day five. Colleagues even asked if I'd had something done to my teeth.

Bram52 · verified purchase

After years of red wine and cigarettes, I didn't have high expectations. The result is subtle but clearly visible.

Tim23 · verified purchase

Simpler than I thought. Gel in, tray on, rinse. No hassle with strips you constantly have to adjust.

Mark41 · verified purchase

I'd tried strips before, but they always slipped. This tray stays put, and the result is much more even.

Fatima29 · verified purchase

Knowing there's a dentist behind it gave me the confidence to try it. It's great that it clearly states how long you can use it.

Lieke26 · verified purchase

Started just in time for my sister's wedding. You can see the difference immediately in the photos, without it looking overly white.

Noor31 · verified purchase

The fifteen minutes is really manageable. I do it while I'm clearing my emails, so I hardly ever forget.

Esther34 · verified purchase

At the dentist, I received a quote for over four hundred euros. This cost a fraction, and I'm just as happy with it.

Marleen48 · verified purchase

Did a second course as maintenance, half a year after the first. My shade is completely back to its original level.
