A healthy 32-year-old woman presented with 2 weeks of black discoloration of the tongue. She denied new medications and tobacco use, but had started using mouthwash containing hydrogen peroxide 1 month earlier. Examination revealed black pigmentation of filiform papillae on the dorsum of her tongue (Fig. 1). The findings were felt to be consistent with black hairy tongue (BHT) secondary to the use of oxidizing mouthwash. The patient was instructed to discontinue the mouthwash and clean her tongue twice daily with normal saline. Within 2 weeks, the discoloration had resolved.
