Bad breath happens to everyone occasionally—but if it’s happening often, it’s more than just an inconvenience. Chronic bad breath, also known as halitosis, affects up to 1 in 4 people and is often a sign of underlying dental or health issues.
At Cool Creek Family Dental, we know how frustrating and even embarrassing this issue can be. That’s why we’re breaking down the top causes of bad breath and showing you exactly how to get rid of bad breath for good.
Top Causes of Bad Breath
1. Poor Oral Hygiene
If you’re not brushing and flossing thoroughly, bacteria and food particles start to accumulate on your teeth, gums, and especially your tongue. These bacteria release sulfur compounds that produce a strong, unpleasant odor.
What to do:
Brush your teeth twice daily with fluoride toothpaste
Use a tongue scraper to clean the back of the tongue
Floss daily to remove food between teeth
Rinse with an antibacterial mouthwash like chlorhexidine or one containing essential oils
Pro tip: Don’t skip flossing—bad breath bacteria love hiding in those tight spaces between teeth.
2. Dry Mouth (Xerostomia)
Saliva naturally washes away food debris and bacteria. But if your mouth is too dry, bacteria can thrive—and that often leads to bad breath. Causes of dry mouth include:
Dehydration
Mouth breathing
Certain medications (antidepressants, antihistamines, blood pressure meds)
Medical conditions like Sjögren’s syndrome
What to do:
Drink plenty of water throughout the day
Avoid alcohol-based mouthwashes and caffeine
Use a humidifier at night if you breathe through your mouth
Ask your dentist about saliva-stimulating products or sprays
3. Certain Foods and Beverages
Foods like garlic, onions, curry, and tuna contain sulfur compounds that are absorbed into your bloodstream and released when you breathe. Coffee, alcohol, and high-sugar diets also contribute to dry mouth and bacterial growth.
What to do:
Brush and rinse after meals
Chew sugar-free gum with xylitol to stimulate saliva
Limit foods known to linger on your breath
Choose fresh produce like apples and carrots—they help cleanse your mouth naturally
4. Gum Disease (Periodontal Disease)
If your bad breath is persistent and comes with bleeding gums, loose teeth, or receding gums, gum disease could be the cause. Bacteria collect in deep pockets around your teeth, where they’re harder to clean.
What to do:
Schedule a professional cleaning every 6 months—or more often if you’re high risk
Consider deep cleaning (scaling and root planing) if your dentist finds signs of gum disease
Use a water flosser to reach below the gum line at home
Important: Gum disease doesn’t just affect your breath—it’s also linked to heart disease, diabetes, and premature birth.
5. Tonsil Stones (Tonsilloliths)
These small, white or yellowish formations are made of hardened bacteria and debris. They get trapped in the crevices of your tonsils and can cause an intense odor, even if your oral hygiene is excellent.
What to do:
Gargle with warm salt water regularly
Use a water flosser on low pressure to gently remove them
If tonsil stones are frequent or severe, talk to your doctor about treatment options
6. Underlying Medical Conditions
Sometimes, bad breath is a red flag for a deeper health issue:
Acid reflux (GERD): stomach acid travels back up the esophagus
Sinus infections/post-nasal drip: mucus drainage encourages bacterial growth
Diabetes: sweet or fruity breath can be a sign of high ketone levels
Kidney or liver disease: can produce a metallic or ammonia-like smell
What to do:
If dental treatment doesn’t resolve the issue, consult your primary care provider
Manage chronic conditions closely with your healthcare team
