Between a quarter and half of the population would be affected by bad breath at some point, according to the National Health Insurance. A staggering figure that deserves attention, especially when you think you’ve tried everything. Morning and evening brushing, dental floss, mouthwash with an intensely mentholated scent: nothing works, this stubborn breath always returns. The most common reflex is then to suspect the stomach, to wonder if digestion plays tricks. Yet, this lead is almost invariably the wrong one. The true origin of the problem hides elsewhere, in a corner of the mouth that regular brushing never truly reaches.
- In 85 to 90% of cases, halitosis originates in the mouth rather than the digestive tract.
- The tongue, where 60% of oral bacteria concentrate, would be responsible for 41% of halitosis cases.
- Cavities, gingivitis, dry mouth, tobacco or certain medications can sustain halitosis even if mouthwash solves the problem.
- Why the mouth is almost always the real culprit
- What your brushing cannot reach

Pourquoi la bouche est presque toujours la vraie coupable
Contrary to widespread belief, the stomach is rarely responsible for unpleasant breath. The numbers from the National Health Insurance are clear: in 85 to 90 % of cases, the origin of halitosis is oral. The mechanism is actually fairly straightforward. Bacteria naturally present in the mouth break down proteins, whether they come from food, saliva, or even cells of the oral mucosa. This degradation releases volatile sulfur compounds, those infamous malodorous molecules responsible for the unpleasant odor of exhaled air. And among all the corners of the mouth, one in particular concentrates the core of the problem: the tongue. Its papillae harbor 60 % of the oral bacteria and would be responsible for 41 % of cases of halitosis of oral origin. It goes without saying that suspecting the stomach first often means looking for the solution in the wrong place.
Ce que votre brossage ne peut pas atteindre
Brushing teeth with care does not always suffice, and for good reason: numerous oral causes completely escape this essential gesture. The heavily coated tongue is the most telling example, since it is rarely thoroughly cleaned during a standard brush. But other problems also slip under the radar: cavities, dental abscesses, gingivitis, periodontitis, or herpetic stomatitis and aphthous ulcers. Dry mouth also deserves special attention, whether linked to mouth breathing, the use of certain medications, or simply dehydration. Defective dental restorations can also perpetuate the phenomenon without us realizing it. Added to this are lifestyle-related factors, often underestimated: excessive consumption of proteins, garlic, onions or spices, alcohol, fasting, or tobacco. So many causes that no mouthwash, even the most scented, could correct permanently.
Les signaux à surveiller avant de multiplier les produits parfumés
Before systematically turning to a new bottle of mouthwash, it may be useful to question the real origin of the problem. Some conditions, rarer but real, can also explain persistent breath. On the ENT side, sinusitis or tonsillitis are among the possible culprits. Pulmonary conditions such as bronchitis, or digestive issues such as gastroesophageal reflux, ulcers, or cirrhosis, can also come into play. Some cancers, diabetes, or chronic kidney disease are also listed among the causes. One detail worth noting: certain medications used in oncology or psychiatry are known to alter breath, which invites checking the medication label if in doubt. Here are the main elements to monitor when halitosis persists despite good hygiene:
- A visibly coated tongue
- A recurring dry mouth sensation
- Dental or gum problems
- Breath that persists despite rigorous brushing and the use of mouthwash
- The taking of medications known to alter breath
When confronted with breath that does not improve despite all efforts, it is better to seek to understand the cause rather than piling on scented products, which mask the odor without ever addressing the root problem. A professional opinion remains often the most reliable way to identify the exact origin of the issue and to provide an appropriate response.
