The Blancs Guide

Expert answers on our formula, safety, and results.

This is our top priority. Blancs were specifically formulated for people who have experienced “zingers” or pain with other brands. We use a balanced, enamel-safe formula that effectively lifts stains without penetrating the nerves, making them the best teeth whitening strips for sensitive teeth.

Most customers notice a visibly brighter smile after just 3 treatments (3 days). For the full “after” effect—removing years of deep-set coffee and wine stains—we recommend completing the full 14-day cycle included in your kit.

Yes. We use the same active whitening ingredients dentists use, but at a level optimized for at-home safety. Blancs are non-abrasive, meaning they rely on oxidation to lift stains rather than scrubbing away your enamel. They are safe for daily use as directed.

Like all whitening products containing peroxide, Blancs are designed to whiten natural tooth enamel only. They will not damage your dental work (caps, crowns, veneers, or bonding), but they will not change the color of artificial materials. We recommend using them to match your natural teeth to your dental work.

With proper care, your results can last 6 months or longer. This depends largely on your lifestyle—drinking coffee, red wine, or smoking will stain teeth faster. To maintain your bright shade, we suggest doing a “touch-up” treatment (using a few strips) every 3–4 months.

You can drink water while wearing Blancs thanks to our advanced “No-Slip” grip. However, you should avoid eating or drinking colored beverages (like juice or coffee) while the strips are on. For the best results, wait 30 minutes after removing the strips before eating or drinking anything that could stain.

While our ingredients are non-toxic, we always recommend consulting with your doctor or dentist before starting any new cosmetic treatment, including teeth whitening, while pregnant or breastfeeding.
