At The Smilery we place scientific innovation and dental expertise at the heart of our formulas. 

Created by a French holistic dentist and developed in our Parisian laboratory, the brand combines  scientific requirements with a modern vision of oral care: considering the mouth as a true living ecosystem.

Our treatments are formulated without peroxide and aggressive abrasives, to respect the integrity of enamel and gum tissues. Our natural microbiome active ingredients are carefully selected for their ability to harmonize, rebalance and revitalize the oral microbiota — a fundamental pillar of a healthy and lasting smile, and gateway to our overall health.

Our principle: revitalize rather than eliminate

Our expert formulas are based on an innovative approach to oral care: acting precisely on the microbiota rather than eliminating everything.

In vitro tests show that the Solidago flower extract targets 7 harmful bacteria—causing inflammation, staining and bad breath—while the prebiotics nourish and stimulate beneficial bacteria.


This double action participates in rebalancing and sustainably revitalizing the microbiota, restoring a healthy and dynamic oral ecosystem.
