Smile Bad breath: causes and how to fix it
Bad breath usually comes from bacteria on the teeth, gums and tongue. Brushing twice a day, cleaning between your teeth and cleaning your tongue fixes most cases.
Common causes
- Plaque and food left on teeth and between them.
- Gum disease and tooth decay.
- A coated tongue.
- Dry mouth, which reduces the saliva that cleans your mouth.
- Smoking and tobacco.
- Strong foods such as garlic and onions, which are temporary.
- Less often, health problems such as sinus or stomach conditions.
What helps
- Brush twice a day for 2 minutes and clean between your teeth daily. See how to brush and floss correctly.
- Gently brush or scrape your tongue.
- Drink water through the day and do not skip meals.
- Clean dentures every day if you wear them.
- Stop smoking.
- Go for regular dental check-ups.
Mouthwash can freshen breath for a short time but does not treat the cause.
When to see a dentist
See a dentist if bad breath continues after a few weeks of good cleaning, or if you also have bleeding gums, a bad taste, loose teeth or pain. If your mouth is healthy, a doctor can check for other causes.
Quick answers
Why does my breath smell even after brushing?
Bacteria on the tongue, gum disease, dry mouth or trapped food between teeth can cause bad breath even after brushing.
Does mouthwash cure bad breath?
No. It masks odour for a short time. Cleaning your teeth, gums and tongue treats the cause.
