What is the first-line treatment for a patient with black hairy tongue?
Show answer and explanation
Correct answer: B. Improved oral hygiene (tongue brushing / essential oil rinses)
First-line therapy is mechanical debridement: tongue brushing/scraping, discontinuation of precipitating agents (smoking, certain mouth rinses, antibiotics when possible), and essential-oil-based rinses. The condition is not fungal or viral, so antifungals and antivirals are not indicated.
