How To Use

After brushing, as the last step.

  1. Fill your mouth with the rinse.
  2. Swish it around your whole mouth for 30 seconds.

You may see residue in the sink. It doesn't always happen: it depends on each mouth.

How often to use

Once a day, after brushing.

When will I see results

Fresh breath from the first use. As for shade, its role is maintenance: with daily use it helps keep teeth white.

Is it safe

It contains hydrogen peroxide at the concentration permitted by EU regulations for over-the-counter sale, and it's alcohol-free. Do not swallow. If you feel any discomfort, stop using it and consult your dentist.

Complies with EU cosmetics regulations.

Most of my patients want a whiter smile they can see straight away. The V34 corrector neutralises yellow tones from the first use.

A whitener you can see working, and that's safe too.

I'm wary of anything that promises fast results. This one I recommend with confidence.

Hydroxyapatite and potassium citrate are what I would choose for sensitive patients anyway. Here they come inside a whitening routine, so enamel is cared for while the tone improves.

1 in 3 people hide their teeth in photos.

Yellowing has an explanation: age, coffee, tea and tobacco. It's not poor hygiene.

The first time I spat and saw what came out, I was stunned. Now I don't go to bed without it.

Coffee and tobacco. With the rinse every night, new stains take much longer to appear.

Other rinses stung like crazy. This one is gentle, and my breath stays fresh until midday.

I use it to keep the white from the strips. Three weeks in and the shade is the same as day one.

Lots of red wine at weekends. With the daily rinse, my shade doesn't dull like it used to.

Tea all day at the office. The rinse at night lifts what the brush misses, and it shows.

Questions

Go to Support Centre
What is the residue I see in the sink?
It may be residue that brushing didn't remove. It doesn't always show up: it depends on each mouth, and not seeing it doesn't mean it isn't working.
When will I see results?
Fresh breath from the first use. On shade, its role is maintenance: with daily use it helps keep your teeth white.
Does it contain peroxide?
Yes: hydrogen peroxide, at the concentration EU regulations allow for over-the-counter sale. It's the only product in the range that contains it.
Is it safe for sensitive teeth?
It's alcohol-free. If you have sensitivity and feel discomfort, stop using it and see your dentist.
How do I use it?
Fill your mouth with the rinse, swish for 30 seconds and spit it out. Once a day, after brushing.
Can I use it with veneers, crowns or implants?
Veneers, crowns and implants don't whiten. The rinse helps maintain the shade of the surrounding teeth. Check with your dentist.
Does it replace brushing?
No. It's the last step, after brushing with your fluoride toothpaste.

Honestly, my teeth look whiter. It pleasantly surprised me, though it's not the nuclear white you see in videos. Happy with the product.

I'm really happy with this teeth whitener. On my first day I already noticed the change, it leaves your teeth shinier and whiter and a really nice taste in your mouth... So I recommend everyone try it!!!

Fast shipping. The product doesn't whiten on the first go, but I imagine after a couple of times it'll reach the white shade
