Greetings! Thank you for your questions.

First and foremost, we truly understand your concerns regarding your symptoms and other health problems you might be facing. From your complaints, black tongue is usually a harmless condition that can be caused by medications, poor oral hygiene, smoking, soft diet, or dry mouth. A black tongue is usually associated with elongated tongue papillae and hence, it is called “black hairy tongue”. The cause is thought to be a change in the normal bacteria in the mouth after using products that contain bismuth or antibiotic treatment.

However, the following answers regarding your current queries are just general descriptions. We need further detail for a complete explanation. Therefore, we greatly suggest that you refer this to your nearest medical doctor for full examination. You may also click on this link (DoctorOnCall) to speak with our doctors online.
