What is the appropriate treatment for hairy tongue (lingua villosa nigra)?
Show answer and explanation
Correct answer: D. Chlorhexidine or oxidizing mouth rinses (essential oils)
Hairy tongue responds to oxidizing mouth rinses, improved oral hygiene, and removal of causative factors (tobacco, antibiotics, poor hygiene).
- A. Systemic antibiotics may actually CAUSE hairy tongue by disrupting normal oral flora — they are not used for treatment.
- B. Nystatin is for candidiasis. While candida can secondarily colonize hairy tongue, antifungal is not the primary treatment.
- C. Surgical debridement is rarely needed. Hairy tongue typically responds to improved oral hygiene and topical measures.
- D. CORRECT. Oxidizing rinses (Listerine/essential oils, dilute H₂O₂, chlorhexidine) reduce bacterial overgrowth and help clean the elongated filiform papillae. Removing causative factors (tobacco, antibiotics) is also essential.
