Gouttières de blanchiment professionnelles prêtes à l'emploi (7 traitements)

Each U-shaped tray comes pre-filled with 8% hydrogen peroxide, the active ingredient that powers the whitening. You place the tray onto your teeth, and as the peroxide goes to work it lifts surface stains over time, gradually revealing a visibly brighter smile. Because the trays come pre-filled, there's nothing to measure or assemble—just apply and wait.

The formula is designed to be gentle on sensitive mouths and enamel while still delivering effective whitening, making it a good option if stronger treatments have bothered you in the past. As with any hydrogen peroxide whitening, some people may notice mild, temporary sensitivity depending on their teeth—if that happens, space out your treatments and check with your dentist if it persists.

The tray has an ergonomic U-shape that fits comfortably onto your upper and lower teeth at once, keeping the whitening formula in even contact across your smile. The formula is also made not to leave any unwanted residue behind, so your mouth feels clean and comfortable after each treatment.

Each kit includes 7 pre-filled treatments—enough for a full whitening course. Since every tray comes ready to use, you can simply work them into your routine one at a time.

Coconut oil adds a smoother, gentler feel to the whitening experience. Infusing it into the formula helps keep the treatment comfortable on your teeth and gums while the hydrogen peroxide does the whitening work.

Whitening happens gradually—the formula lifts surface stains over time, so your smile should look progressively brighter as you work through the treatments rather than all at once. How noticeable and long-lasting the results are can depend on factors like diet and oral hygiene habits, and individual results may vary.
