How to have fresh breath all day long?

Published on July 08, 2026

Do you brush your teeth morning and night, but your breath isn't fresh a few hours later? You're not alone. Bad breath, also called halitosis, affects a large part of the population and remains one of the most common oral health concerns.

Contrary to popular belief, bad breath isn't always linked to poor hygiene. In most cases, it's the result of a bacterial imbalance in the mouth. To achieve lasting fresh breath, it's therefore essential to understand its origin rather than simply masking the odors.

1. Why do we have bad breath?

In nearly 90% of cases, bad breath originates in the mouth.

Certain bacteria found on the tongue, between the teeth, or on the gums break down food residue and produce volatile sulfur compounds. These are responsible for unpleasant odors.

Several factors contribute to their development:

  • a loaded language
  • a dry mouth
  • insufficient interdental cleaning,
  • an imbalance of the oral microbiota,
  • tobacco,
  • some very smelly foods.

Bad breath is therefore often a symptom of an unbalanced oral environment rather than a simple problem of freshness.

2. Mistakes that prevent you from having fresh breath

The first mistake is trying to mask the odors without addressing their origin.

Chewing gum, mint candies, or alcohol-based mouthwashes provide an immediate feeling of freshness, but their effect is temporary. Some mouthwashes can even dry out the mucous membranes and cause unpleasant odors to return a few hours later.

Another common mistake is neglecting the tongue. Yet, it is one of the main bacterial reservoirs in the mouth.

Finally, many people forget to clean between their teeth. However, the bacteria responsible for bad breath thrive precisely in these hard-to-reach areas.

3. The ideal routine to keep your breath fresh all day

Long-lasting fresh breath relies on a complete routine.

Brushing remains essential, but it must be complemented by cleaning the tongue and interdental spaces.

The daily use of a tongue scraper It helps eliminate a large portion of the bacteria responsible for bad odors.

In addition, the The Smilist Purifying Bi-Phase Micro-Oil It helps purify the mouth while respecting the oral microbiota thanks to its prebiotic-enriched formula. Inspired by oil pulling, it helps rebalance the oral environment without irritating it.

For busy days, travel, or after a meal, the The Smilist Purifying Mouth Spray allows you to quickly regain a feeling of freshness while respecting the natural balance of the mouth.

The goal is not to mask odors for a few minutes, but to create a healthier oral environment in the long term.

In Summary

  • Bad breath is usually caused by certain bacteria present in the mouth.
  • Brushing alone is not always enough to remove them.
  • Cleaning the tongue and interdental spaces is essential.
  • A routine that respects the microbiota helps to restore fresh breath in the long term.
