Numbness of the tongue and loss of taste is when you feel a swollen, burning sensation on your tongue and loss of appetite. The most common causes of tongue numbness are allergic reactions to certain foods, low calcium levels in the blood, bacterial infections such as Lymes disease, or conditions related to the nervous system.

Prolonged burning tongue and dry mouth can be a symptom of some diseases such as oral infection, tongue fungus, depression or neurological disorders.
