What Causes Bad Breath
Bad breath is embarrassing, but it is also very common and usually fixable. Understanding the cause is the first step to solving it for good.
Common Causes
Bacteria on the tongue: The back of your tongue has a rough surface that traps bacteria. This is the number one cause of bad breath and the most overlooked.
Food between teeth: Trapped food particles decompose and produce odor. Flossing removes what your brush misses.
Gum disease: Infected gum pockets harbor bacteria that produce strong odors. If your breath smells bad despite good hygiene, gum disease might be the cause.
Dry mouth: Saliva naturally cleans your mouth. When your mouth is dry (from medications, mouth breathing, or dehydration), bacteria thrive.
Certain foods: Garlic, onions, and coffee cause temporary bad breath. This is normal and goes away on its own.
What to Do Now
- Clean your tongue daily. Use a tongue scraper or the back of your toothbrush. Focus on the back third of your tongue where most bacteria live.
- Floss every day. Removing trapped food between teeth eliminates a major source of odor.
- Check for underlying issues with DentaSmart. Upload a photo to check for signs of gum disease or decay that might be causing persistent bad breath. If it continues despite good hygiene, see a dentist.
