In simple words

Halitosis is an unpleasant smell on the breath. It is usually related to bacteria and food debris in the mouth, teeth, gums, or tongue.

Clinical Meaning

Persistent bad breath can be a sign of gum disease, tooth decay, dry mouth, tonsillitis, reflux, or another issue needing dental or medical care.

Common Causes

  • Plaque on teeth or tongue, gum disease, tooth decay, or a dental infection
  • Dry mouth, smoking, alcohol, fasting, or strong-smelling foods and drinks
  • Tonsillitis, acid reflux, or another nose, throat, or digestive condition
  • Poorly cleaned dentures

Clinical Red Flags

Seek urgent medical attention at an emergency department or primary care clinic if you present with any of the following symptoms:

  • See a dentist for bad breath that persists after several weeks of good oral care, or for toothache, painful or bleeding gums, swollen gums, loose adult teeth, or denture problems.
  • Seek urgent dental or medical advice for facial swelling, fever, severe mouth pain, trouble swallowing, or breathing difficulty.
  • A mouth ulcer, lump, or red or white patch lasting more than three weeks should be checked.

Lifestyle & Diet Support

Brush teeth and gums twice daily with fluoride toothpaste, clean between teeth daily, gently clean the tongue, keep dentures clean and out at night, drink water, and avoid smoking. Regular dental check-ups help prevent oral causes.
