Can antibiotics cause a black hairy tongue?
4 doctors weighed in across 2 answers
Black Hairy Tongue: Yes, the use of antibiotics changes the flora or normal bacterial composition in the mouth and can result in changes in the papilla that cover the surface of the tooth. For more information as to causes and discussion of this condition, see: http://www.mayoclinic.org/diseases-conditions/black-hairy-tongue/basics/causes/con-20034518
