What Are the Symptoms of Black Hairy Tongue?
Other than the appearance of the tongue, most people with black hairy tongue don’t have any symptoms or feel any discomfort. The exception is when there is too much growth of the yeast Candida albicans, which can cause a burning sensation on the tongue. This burning sensation is called glossopyrosis. Some people complain of a tickling feeling in the back of the roof of the mouth, a metallic taste in their mouth, or nausea. In more severe cases, the condition may lead to a gagging feeling. Sometimes, food getting caught inside the extra-long papillae can cause bad breath.
