Symptoms of a burning or burn on the tongue include pain, redness and swelling, notes Healthline. More severe burns can result in blisters and even blackened skin. Those with burning tongue syndrome experience the burning pain associated with a tongue burn, but without the hot food or drink that causes it. This burning sensation is often accompanied by a bitter taste, dry mouth and recurring burning pain.
Those with secondary burning tongue or burning mouth syndrome often have a medical condition that causes it, such as nerve damage, food allergies, vitamin deficiencies, oral yeast infections or hormone imbalances, explains Healthline. Diabetes, gastroesophageal reflux disease and depression can also result in burning tongue. Primary burning tongue syndrome has no known cause. A doctor often treats burning tongue by treating the underlying cause. For instance, if acid from gastroesophageal reflux disease is burning the tongue, a patient takes drugs to reduce acid production and prevent the burning.
Treating a burn on the tongue, depending on the severity, includes rinsing the area, gargling salt water, and taking over-the-counter medications to reduce inflammation, advises Healthline. Placing a wet, cold cloth on the area or sucking on ice chips can help to reduce pain. An individual only needs to get medical aid if the area becomes infected and drains puss or causes a fever.
