Your questions, our answers
How do I use it?
Dampen your brush, dip it in the powder, brush for 2 minutes, then rinse. Follow with your usual toothpaste. Use twice a week.
How long does it take to see results?
Surface stains (coffee, tea, tobacco) visibly fade over the first few weeks of regular use. And a clear improvement is observed after 14 days.
Does it damage the enamel?
No. Our baking soda formula is one of the gentlest available. It is gentler than a conventional whitening toothpaste and incomparable to abrasive charcoal powders.
I have sensitive teeth or gums, can I use it?
Yes. The formula contains neither peroxide (responsible for the sensitivities caused by whitening kits) nor SLS (an irritating sulfate for the gums).
What's the difference with a charcoal powder?
Charcoal is abrasive: it whitens by scratching the surface of the tooth, which weakens the enamel over time. Our powder removes stains without scratching.
What's the difference with a peroxide kit?
Peroxide chemically whitens but often causes sensitivity, and its concentration is very limited over-the-counter in Europe. Our powder acts on surface stains, painlessly and without hassle.
How long does a pot last?
Around 6 months, with 2 uses per week.
What does it taste like?
Fresh mint, with a characteristic hint of baking soda that disappears upon rinsing. The clean feeling, however, remains.
Does it replace my toothpaste?
No, it's a supplement: the powder takes care of stains and shine, your fluoride toothpaste takes care of cavity protection. The perfect duo.
