You brushed. You might even have flossed. And your breath still isn't where you want it. Bad breath is one of the most-searched embarrassing health questions, and brushing alone often doesn't solve it.
The usual culprits
- Your tongue. Bacteria collect on the back of the tongue, and a toothbrush doesn't always reach them.
- Dry mouth. Saliva washes bacteria away. Mornings, mouth breathing, some medications and not drinking enough water all dry your mouth out.
- Food and drink. Garlic, onions, coffee and alcohol can linger for hours.
- Smoking and vaping. Both cause odor and dry your mouth.
- Gum disease or cavities. Bacteria trapped around gums and teeth are a common cause of breath that won't go away.
- Things outside your mouth. Postnasal drip, sinus problems and acid reflux can all affect your breath.
What helps
- Brush twice a day and floss once a day.
- Clean your tongue with your toothbrush or a tongue scraper.
- Drink water through the day, and chew sugar-free gum to keep saliva flowing.
- Try an alcohol-free mouthwash. Alcohol can dry your mouth out.
- Keep breath strips or mints handy for meetings and dates.
- See your dentist for regular cleanings.
When to get checked
If bad breath sticks around despite good habits, see your dentist first. Gum disease is a common cause, and it's treatable. If your dentist rules out your mouth, your doctor can check for sinus or reflux problems.
