Fissured tongue, also known as lingua plicata, furrowed tongue, or plicated tongue, is a prevalent condition characterized by distinct fissures or grooves on the surface of the tongue. These fissures can vary in size, location, and depth from person to person. While a fissured tongue can sometimes be an indication of an underlying health issue, it is generally considered a harmless condition.
Symptoms of Fissured Tongue
Fissured tongues can have different appearances, but they all share a common characteristic – grooves that range in depth from two to six millimeters. These grooves are usually found in the middle section of the tongue, but they can extend across its entire surface. Although the appearance of these grooves may be concerning, they typically do not cause any pain. However, they can become a breeding ground for food particles, leading to inflammation, a burning sensation, and bad breath.
Causes
Understanding the exact cause of fissured tongue remains a challenge as research is still ongoing. Although no conclusive evidence has been found, studies have suggested that the condition may have a hereditary component. Additionally, researchers have observed certain conditions that tend to be more prevalent in individuals with fissured tongues. However, the extent of correlation between these conditions and fissured tongues remains unclear.
