Breath odor

Alternative Names:
Bad breath; Halitosis

Home Care:

Use proper dental hygiene (especially flossing), and remember that mouthwashes are not effective in treating the underlying problem.

Fresh parsley or a strong mint are often effective ways to fight temporary bad breath. Avoid smoking. Otherwise, follow prescribed therapy to treat the underlying cause.



Call your health care provider if:
  • Breath odor persists and there is not an obvious cause (such as smoking or eating odor-causing foods).
  • You have breath odor and signs of a respiratory infection, such as documented fever, cough, or facial pain with nasal discharge


What to expect at your health care provider's office:

The medical history will be obtained, and a physical examination performed.

Medical history questions documenting breath odor in detail may include:

  • Is there a specific odor?
  • Is there a fishy smell?
  • Does the breath smell like ammonia or urine?
  • Does the breath smell like fruit or is there a sweet-chemical smell?
  • Does the breath smell like feces?
  • Does the breath smell like alcohol?
  • Has the person recently eaten a spicy meal, garlic, cabbage, or other "odorous" food?
  • Does the person take vitamin supplements?
  • Does the person smoke?
  • Does good oral hygiene improve the odor?
  • What home care measures have been tried? How effective are they?
  • Is there a recent sore throat, sinus infection, tooth abscess, or other illness?
  • What other symptoms are also present?

The physical examination will include a thorough examination of the mouth and the nose. A throat culture may be taken if the patient has a sore throat or mouth sores.

In rare cases, diagnostic tests that may be performed include:

Antibiotics may be prescribed for some conditions. For an object in the nose, the doctor will use an instrument to remove it.
