Nobody wants to talk about bad breath — but your dentist does.
Halitosis affects an estimated 1 in 4 people, yet it remains one of the most under-discussed oral health concerns. The good news? It’s almost always treatable once you understand what’s driving it.
The real culprit: bacteria
Your mouth is home to hundreds of bacterial species. Most are harmless, but some — particularly those that thrive in low-oxygen environments like the back of the tongue, between teeth, and beneath the gumline — produce volatile sulphur compounds (VSCs) as a byproduct. These compounds are the primary source of that unpleasant odour. Gum disease and untreated cavities create even more hiding spots for odour-causing bacteria to multiply.
How diet plays a role
What you eat directly affects your breath. Garlic, onions, and spicy foods contain aromatic compounds that enter the bloodstream and are exhaled through the lungs — no amount of brushing will fully mask them until your body has processed them. A low-carbohydrate diet can trigger “keto breath,” a distinct acetone-like smell caused by the breakdown of fats. Alcohol and coffee also dry out the mouth, reducing saliva — your body’s natural bacteria-fighter.
Hygiene habits that make a difference
Most cases of halitosis can be significantly improved with consistent oral hygiene:
- Brush twice daily — including the surface of your tongue, where bacteria love to accumulate
- Floss every day to remove food debris and plaque between teeth
- Stay hydrated to keep saliva production up
- Replace your toothbrush every three months
- Visit your dentist regularly for professional cleanings and early detection of gum disease
When to see a dentist
If fresher breath doesn’t follow improved hygiene after a couple of weeks, it may signal an underlying issue like periodontal disease, dry mouth syndrome, or even a systemic condition. A dental check-up is the fastest route to a lasting solution.
