Visit a dentist to rule out gum disease or underlying conditions

Schedule a dental checkup if bad breath persists despite consistent oral hygiene. A dentist can identify and treat underlying causes that home care cannot resolve, including periodontal (gum) disease, cavities, abscessed teeth, ill-fitting dental appliances, and oral infections. Persistent halitosis is one of the early warning signs of gum disease.

Why It Works

The ADA recommends regular dental visits for professional cleaning and examination. Periodontal pockets -- gaps between the gums and teeth caused by gum disease -- harbor bacteria deep below the gumline where brushing and flossing cannot reach. Professional scaling and root planing remove these bacterial deposits. In some cases, persistent bad breath originates from non-oral sources (sinus infections, gastroesophageal reflux, tonsil stones, or metabolic conditions), and a dentist can help identify when a medical referral is appropriate.

Tips

• See a dentist at least twice a year for routine cleanings, or more often if you have gum disease
• Mention bad breath specifically during your visit -- many patients feel embarrassed but dentists assess it routinely
• Tonsil stones (tonsilloliths) are a commonly overlooked cause of halitosis; ask your dentist to check
• If dental causes are ruled out, your dentist may refer you to a physician to evaluate gastric, sinus, or systemic conditions
• Professional cleanings remove calcified tartar that cannot be removed by brushing at home
