5 myths about teeth whitening you should forget
Whitening damages enamel. It is painful. Results do not last. Online kits work just as well. It is not a medical procedure. All false — here is why.

Whitening damages enamel
Professional gels act on pigments inside the enamel without attacking the surface. Unlike abrasive consumer toothpastes, clinical actives penetrate gently to break down deep stains — leaving the enamel structure intact.
It is inevitably painful
Post-treatment sensitivity exists but it is temporary and increasingly rare with latest-generation gels. Highly hydrated, neutral-pH formulas like WhitenPro Sensitive are specifically designed to eliminate all sensitivity.
Results do not last
Professional whitening lasts 12 to 24 months on average depending on habits (coffee, tea, tobacco). A suitable maintenance toothpaste significantly extends results. It is a lasting treatment, not a short-lived fix.
Online kits do the same thing
Online kits use universal trays that fit poorly. Gel leaks, contact is uneven, results are inconsistent. In the practice, trays are custom thermoformed from your impressions — this precision makes all the difference.
It is not a medical procedure
In France, whitening with concentrated actives is strictly reserved for dental surgeons. It is not a trivial cosmetic procedure — it is an act regulated by European legislation that requires a prior diagnosis and professional follow-up.
