What Causes Bad Breath?

Occasional bad breath happens to everyone, but chronic bad breath (halitosis) that doesn't go away with brushing and mouthwash can be embarrassing and may indicate an underlying dental or health issue. The good news is that most causes of bad breath are treatable.

Common Causes

• Poor oral hygiene allowing bacteria to build up
• Gum disease (a leading cause of persistent bad breath)
• Food particles trapped between teeth
• Dry mouth (reduced saliva production)
• Smoking or tobacco use
• Certain foods like garlic and onions
• Dental infections, cavities, or abscesses
• Tongue coating of bacteria

When to See a Dentist

If bad breath persists despite good oral hygiene, or if it's accompanied by bleeding gums, toothache, dry mouth, or a bad taste, see a dentist. Chronic halitosis is often a sign of gum disease or decay that needs treatment.

Getting Fresh Breath Back

Treatment may include professional cleaning to remove tartar, treating gum disease, filling cavities, or recommending specific oral care products. Sometimes bad breath originates from the tongue — we can show you proper tongue cleaning techniques.
