Do you have bad breath that doesn’t go away even after brushing your teeth?
Persistent bad breath after brushing is pretty common, and it’s often caused by something other than “dirty teeth.” Some of the most common causes are:
- Bacteria on the tongue (especially the back of the tongue)
- Gum disease or plaque buildup
- Dry mouth
- Tonsil stones
- Sinus infections or post-nasal drip
- Smoking/vaping
- Certain foods or diets
- Acid reflux or stomach issues (less common than people think)
A few things that often help:
- Brush twice daily and floss once daily
- Clean your tongue with a scraper or toothbrush
- Stay hydrated
- Use an alcohol-free mouthwash
- Replace your toothbrush regularly
- Get a dental cleaning if it’s been a while
If the smell continues for more than a couple of weeks despite good oral hygiene, it’s a good idea to see a dentist. Persistent bad breath can sometimes point to gum disease, cavities, or another medical issue.
