Like the gut, the mouth is home to a microbiome: a collection of naturally occurring micro-organisms (bacteria, yeasts, non-pathogenic viruses) that play a key role in our health.

It is estimated that a healthy adult has more than 700 different species of bacteria in their mouth!

-> These micro-organisms live in balance on the teeth, gums, tongue, and oral mucosa. When properly balanced, they protect your mouth from external aggressors.

Why is the microbiome essential to your dental health?

1. It acts as a protective barrier

Beneficial bacteria prevent pathogens (cavity-causing bacteria, those responsible for inflammation, etc.) from proliferating. A healthy microbiome is your first line of defence against cavities, bad breath, and periodontal disease.

2. It maintains a balanced pH

The microbiome helps regulate oral acidity. An overly acidic pH encourages enamel demineralisation. A good microbial balance = a lower risk of cavities.

3. It supports local immunity

A diverse microbiome stimulates natural defences and prevents chronic inflammation of the gums.

What disrupts the microbiome (often without us realising)

• Aggressive mouthwashes (alcohol-based)
• Overly abrasive toothpastes
• A diet high in ultra-processed, sugary, or acidic foods
• Stress, certain medications (antibiotics, the pill)
• Insufficient saliva (xerostomia)

By eliminating all bacteria, including the "good" ones, we weaken the oral ecosystem… and open the door to imbalance.

How to care for your oral microbiome every day

1. Choose products that respect the natural flora

Out with the harsh products! Opt for a gentle, microbiome-friendly routine.

At The Smilist, our rituals are formulated without fluoride, without alcohol, and enriched with prebiotics and minerals that nourish and strengthen the protective microbiome!

2. Maintain a gentle but regular hygiene routine

Brushing twice a day, using dental floss or interdental brushes, staying hydrated… All of this helps remove excess plaque without destroying the microbial balance.

As a complement, our Purifying Biphasic Micro-Oil helps soothe and rebalance the mouth, without alcohol or harsh ingredients!

3. Stimulate saliva production

Saliva is an essential player in the microbiome. It hydrates, nourishes, and regulates the oral environment. Drink regularly, chew slowly, and avoid products that dry out the mouth (tobacco, alcohol, aggressive mouthwashes).

The Smilist Purifying Mouth Spray helps freshen breath while supporting microbiome balance. A true essential to keep in your bag.

In summary: why this is a revolution

Adopting a microbiome-friendly approach means shifting:

❌ from a "kill all bacteria" mindset
✅ to a "cultivate the mouth's biological balance" mindset

This more natural, more intelligent, and more sustainable vision of oral health not only helps prevent cavities and gingivitis, but also helps support your immunity, your breath, and your overall daily comfort.
