Did you know that a kiss means exchanging 80 million bacteria?

Published on February 14, 2025

It's Valentine's Day, and Valentine's Day means moments of intimacy — and passionate kisses! But did you know that a single kiss can involve the exchange of 80 million bacteria? Fascinating, isn't it?

Don't panic — not all of these bacteria are harmful! In fact, many of them play a role in maintaining a healthy, balanced oral microbiome. So, how can you make sure this exchange is as healthy as it is romantic? Here are our tips.

Why does your mouth deserve attention?

Your mouth is far more than a tool for speaking or eating. It is the meeting point of an incredible diversity of micro-organisms that play a key role in your overall health.

A balanced oral microbiome contributes not only to fresh breath, but also to the prevention of oral health problems such as gum disease, as well as wider health issues like cardiovascular disease!

Take great care of your mouth to stay in good health!

Adopt a tailored oral care routine

1. Don't underestimate tongue cleaning
Did you know that the tongue harbours the majority of bacteria present in your mouth? Use a tongue scraper daily to remove debris and reduce the odour-causing compounds responsible for bad breath — our favourite is the one from The Smilist.

2. Choose gentle, natural products
Opt for alcohol-free toothpastes and mouthwashes to preserve the balance of your oral microbiome. For example, a tongue serum formulated with purifying actives can make all the difference.

3. Stay well hydrated
A dry mouth is a breeding ground for bacteria. Remember to drink plenty of water throughout the day to stimulate saliva production — your best natural ally against imbalances.

4. Eat in a way that's friendly to your oral microbiome
Foods rich in probiotics, such as natural yoghurt or fermented vegetables, can boost the diversity of your beneficial oral bacteria. And limit sugary foods, which feed harmful bacteria!
