ORAL HYGIENE MEASURES AND TONGUE SCRAPING
Brush teeth twice daily with fluoride toothpaste, floss interdentally daily, scrape posterior tongue dorsum gently with a tongue cleaner, and maintain adequate oral fluid intake - Ongoing continuous practice
Assist young children with daily tooth brushing and tongue cleaning; check for nasal foreign bodies if sudden severe unilateral odor

Over 85% of halitosis originates from bacterial coat on the posterior tongue and interdental space; mechanical cleaning directly targets the primary source
- Refer to dentist if halitosis persists despite good oral hygiene to rule out periodontal disease or dental caries.
- Evaluate for extra-oral causes: chronic sinusitis, tonsilloliths, GERD, diabetes (ketoacidosis), or hepatic/renal insufficiency.
