ORAL MICROBIOTA

Fresh breath starts with your microbiota.

Because masking odors isn't enough. In most cases, bad breath stems from an imbalance in the oral microbiota.

Written by a holistic dentist

01 /The real cause

These are your bacteria, not your meal.

Bad breath is, in most cases, linked to the activity of bacteria present in the mouth—especially on the tongue and between the teeth. By breaking down food residue, they produce volatile sulfur compounds, which are responsible for unpleasant odors.

80% of bad breath cases are thought to be linked to an imbalance of the oral microbiota, rather than a lack of hygiene.

02 /Language Focus

They are in their element when it comes to language.

The tongue is the area of ​​the mouth with the highest concentration of odor-causing bacteria: its surface texture (the papillae) easily traps bacteria, dead cells, and food particles, giving it a whitish appearance. It is estimated that approximately 80% of halitosis cases are linked to bacteria present on the tongue—yet it is the area most often neglected during daily brushing.

04 /The trap of quick fixes

Chewing gum, alcohol mouthwash: they mask, they do not treat.

These solutions provide an immediate feeling of freshness, but they don't rebalance the oral microbiota. Worse, alcohol-based mouthwashes dry out the mouth and perpetuate the problem they promise to solve.

05 /Our approach

The Smilist targets the bacteria responsible, without harming the good ones.

This is the logic behind The Smilist's Intense Purifying Tongue Serum: a formula with Zinc-Biotic Complex (zinc mineral and prebiotics) and Phyllanthus berry extract, designed to reduce odor-causing bacteria while supporting those essential for a healthy oral microbiome. Apply a few drops to the tongue every morning after brushing.

06 /Who is The Smilist?

The Smilist, pioneers in oral microbiota.

The Smilist is a 100% natural and certified organic oral care brand founded on a single conviction: to rebalance the oral microbiome rather than mask the symptoms. Fresh breath is first and foremost a reflection of a healthy and balanced mouth.

07 /The team behind the brand

Designed by a holistic dentist in Paris.

The Smilist was co-founded by Christiane, a holistic dentist, alongside a cosmetics expert and an image consultant. Its formulas are conceived and developed in Paris, then manufactured in France.

06 /A routine, not an isolated gesture

Long-lasting fresh breath requires a complete routine, not just one action.

Gentle and regular brushing, flossing, tongue cleaning—often forgotten—and microbiome-friendly care. It's the combination of these practices that restores balance, not a spray used alone.
