Around 80-90% of bad breath comes from bacteria inside the mouth. Food and bacteria trapped on the back of the tongue, between teeth and under the gums release foul-smelling gases.
Causes
- A white coating on the tongue
- Food stuck between teeth
- Gum disease or cavities
- Not drinking enough water; a dry mouth
- Smoking, onions and garlic
Solutions
- Clean your tongue daily with a scraper or brush
- Floss between your teeth
- Drink plenty of water
- Sugar-free gum helps increase saliva
- Get regular professional cleanings
Is mouthwash enough?
Mouthwash masks the smell for a while but does not remove the cause. Brushing, flossing and cleaning the tongue are the real fix.
When to see a dentist
If bad breath continues despite good care, see a dentist — they may suggest checking for other causes.
