If previously normal breath turns into halitosis, causes could include:
Abscessed tooth Alcoholism Cavities Dentures Drugs
Paraldehyde Triamterene and inhaled anesthetics Insulin - injection
Food or beverages consumed (such as cabbage, garlic, raw onions, or coffee) Foreign body in the nose (usually in children)
Often (but not always) there is a white, yellowish, or bloody discharge from one nostril
Gum disease (gingivitis, gingivostomatitis) Impacted tooth Lung infection Poor dental hygiene Sinusitis Throat infection Tobacco smoking Vitamin supplements (especially in large doses)
Diseases that may be associated with breath odor (not presented in order of likelihood -- some are extremely unlikely):
Acute necrotizing ulcerative gingivitis Acute necrotizing ulcerative mucositis Acute renal failure Bowel obstruction (can cause breath to smell like feces) Bronchiectasis Chronic renal failure (can cause breath to smell like ammonia) Diabetes (fruity or sweet chemical smell with ketoacidosis) Esophageal cancer Gastric carcinoma Gastrojejunocolic fistula (fruity-smelling breath) Hepatic encephalopathy Diabetic ketoacidosis Lung abscess Ozena, or atrophic rhinitis Periodontal disease Pharyngitis Zenker's diverticulum
