SmileScoutMost lasting bad breath is made in the mouth. Bacteria break down leftover food and dead cells and release sulphur compounds. Brushing the outer surfaces of the teeth twice a day is essential — but it often misses the two places odour loves: the tongue and the gaps between teeth.
A dry mouth (from mouth-breathing, some medicines, or not drinking enough) makes it worse, because saliva is the mouth's natural rinse. Gum disease and cavities can also feed the smell.
A better daily routine
- Brush twice daily, including a gentle sweep over the tongue
- Clean between teeth every day
- Stay hydrated; go easy on coffee, alcohol, and tobacco
- Don't skip breakfast — an empty, dry mouth overnight is why morning breath is so common
If the smell is still there after two weeks of this routine, see a dentist. Mints only mask the problem. A check-up can find gum pockets, decay, or a coated tongue that need treating rather than covering up.
