What Are Some Causes of Stinging in the Tongue?

Some causes of stinging in the tongue include a physical burn on the tongue, primary burning mouth syndrome or secondary burning mouth syndrome, according to the Cleveland Clinic and Healthline. Secondary burning mouth syndrome is often caused by an oral yeast infection, dry mouth, geographic tongue, oral lichen planus, anxiety, dentures, nerve damage, allergic reactions, vitamin deficiencies, depression and stomach acid conditions, such as GERD, notes Healthline.

Primary burning mouth syndrome is when a person feels a burning or tingling sensation in their mouth around the gums, tongue, teeth or lips even though there is no reason for the sensation, reports the Cleveland Clinic. A burn on the tongue can be caused by drinking or eating something that is far too hot.
