Short answer
Bad breath (halitosis) usually comes from bacteria in the mouth, and often from the tongue, gums or between the teeth. Causes include poor cleaning, gum disease, dry mouth, certain foods and tobacco. If it lasts, see a dentist to find the cause, because mouthwash alone only masks it.
What causes bad breath?
- Bacteria on the teeth, between the teeth and on the tongue.
- Gum disease.
- Dry mouth.
- Strong foods such as onions and garlic, and drinks such as coffee.
- Smoking and tobacco.
- Some medications.
- Less often, infections or medical conditions outside the mouth.
When to see a dentist
See a dentist if bad breath lasts despite good brushing and cleaning, if your gums bleed or are swollen, or if you notice a bad taste or a sore in your mouth. Because there are many causes, finding the right one matters.
How does a dentist find the cause?
The dentist asks about your habits and health, examines your teeth, gums and tongue, and looks for decay, gum disease or infection. If the cause seems to be outside the mouth, they may suggest you see your doctor.
What helps?
- Brush twice a day and clean between your teeth daily.
- Clean your tongue gently.
- Drink water through the day and talk to your dentist about dry mouth.
- Do not smoke.
- Treat gum disease or decay if they are present.
- Keep regular check-ups.
Mouthwash can freshen breath for a short time, but it does not treat the cause.
