Bad breath (dentists call it halitosis) affects everyone at least occasionally — and many people in silence, not daring to bring it up. The good news: in the vast majority of cases it comes from the mouth itself, which means the right routine is enough to neutralise it. Here are the real causes, the false solutions, and the plan of action.
Where does bad breath come from?
The main culprit: bacteria that break down food residue and dead cells, releasing volatile sulphur compounds — the ones that smell of eggs or cabbage. They thrive:
- on the tongue, especially towards the back, in its whitish coating;
- between the teeth, where the brush never reaches;
- under the gum line when plaque builds up;
- in a dry mouth: saliva is your natural cleanser — at night its production drops, hence morning breath, which is perfectly normal.
Add to that the occasional causes (garlic, onion, coffee, tobacco, fasting) and, more rarely, medical ones (ENT or digestive). If heavy breath persists despite impeccable hygiene, talk to your dentist and then your doctor.
The false solutions that mask without treating
- Chewing gum and mint sweets: a twenty-minute veil of mint over a bacterial problem — handy as a stopgap, useless as a treatment;
- Alcohol-based mouthwashes used repeatedly: alcohol dries the mouth out… and a dry mouth smells stronger afterwards;
- Brushing harder: bad breath cannot be scrubbed away, it is dislodged with method.
The routine that really neutralises it
- Two two-minute brushings a day, gum line included, with a fluoride toothpaste that combines cleaning power and real freshness — that is the job of our Classic Mint, with its clean mint and 1450 ppm fluoride;
- The tongue too: gentle brushing from back to front, or a tongue scraper, removes the coating where the sulphur-producing bacteria live;
- Interdental cleaning in the evening: floss, interdental brushes or a water flosser — the spaces between your teeth account for a huge share of the surfaces to clean;
- Water throughout the day: a hydrated mouth is a mouth that cleans itself;
- Regular scaling at the dentist to remove established tartar, a favourite hideout for bacteria.
The discreet test: lick the inside of your wrist, let it dry for five seconds, then smell it. It is far more reliable than breathing into your hand.
Rushed morning, big evening: the emergency kit
Alongside your core routine: a quick brush (even 60 seconds beats nothing), a large glass of water, and if needed a sugar-free chewing gum to stimulate saliva — not to mask. Coffee on an empty stomach and a cigarette right before a meeting are, for their part, the two classic traps.
Timing matters too: we explain the best time to brush your teeth.
FAQ — bad breath
Why do I have bad breath in the morning even though I brush at night?
Saliva production drops during sleep: bacteria work all night without being rinsed away. It is normal and it disappears with your morning brushing.
Is toothpaste enough against halitosis?
It is the foundation, but the winning trio is brushing + tongue + interdental cleaning. Breath that stays heavy despite this complete routine deserves a professional opinion.
Are strong mint toothpastes better against bad breath?
Mint provides the sensation of freshness, but it is the cleaning (fluoride, action on plaque, consistency) that tackles the cause. Ideally: both in the same tube.
In summary
Bad breath is 90 % decided in the mouth, and it is won with a complete routine rather than with minty tricks.
