Black hairy tongue is usually reversible and has no long-term sequelae as long as the precipitating agent is discontinued and the patient practices good oral hygiene....Within 4 weeks after the minocycline was stopped, her tongue returned to its normal color (Panel B). #NEJM #photo #clinical #black #hairy #tongue #discoloration #oral
