ORAL HYGIENE MEASURES AND TONGUE SCRAPING [1st line] Adult 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 Peds Assist young children with daily tooth brushing and tongue cleaning; check for nasal foreign bodies if sudden severe unilateral odor Source ADA Council on Scientific Affairs: Management of Oral Malodor 2021 Why Over 85% of halitosis originates from bacterial coat on the posterior tongue and interdental space; mechanical cleaning directly targets the primary source Caution 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. 2. REFERRAL & SAFETY-NETTING (NO DRUG THERAPY) [1st line] Adult Source Halitosis - disease-level clinical article (halitosis-clinical.txt) Why Carries the referral criteria and warning signs for this condition, which apply whichever treatment is chosen. Caution RED FLAG - Fruity/acetone breath odor can signal diabetes (ketoacidosis) and ammoniacal breath odor can signal uremia/renal failure - systemic causes needing urgent recognition and a different pathway than oral hygiene measures. 3. CHLORHEXIDINE [add-on - not a substitute] Adult Rinse mouth with 10 mL of 0.12% or 0.2% solution for 1 minute twice daily, separated from toothpaste by rinsing in between x 1-2 weeks maximum per course Peds Over 12 years: 10 mL twice daily (Children > 12 years: 10 mL twice daily. Not recommended in young children who may swallow mouthwash) Source Corsodyl 0.2% Mouthwash SmPC sections 4.2 and 4.4 (eMC product 529) Why Antiseptic mouth rinse with broad antibacterial activity against the oral bacteria that produce volatile sulphur compounds; added to routine brushing and tongue cleaning as an adjunct, not a replacement for mechanical oral hygiene. Caution Do not swallow oral rinse solution. Prolonged use (> 2 weeks) causes temporary brown staining of teeth and tongue, and transient taste alteration. Wait at least 30 minutes between tooth brushing and chlorhexidine rinse (or rinse thoroughly with water), as toothpaste surfactants (SLS) inactivate chlorhexidine (BNF 86). Do not use straight after toothpaste - it inactivates chlorhexidine. Separate the two, rinsing the mouth in between, or use them at different times of day. A course of about one month is what the label describes; staining of the teeth is temporary.
