A woman in her 50's is suffering from, “black hairy tongue” after she was involved in a car accident which crushed her legs. She was given antibiotics to help the healing process after the crash, several days later she realized her tongue darkened black and fuzzy and also reported being nauseous and having a “bad taste in her mouth.” Doctors believe that her medication was the cause, this can also be traced to by poor oral hygiene, alcohol consumption and smoking.
