Fissured tongue is a condition where there are grooves or cracks, sometimes painful, on the surface of the tongue. These grooves are usually positioned parallel to and crossing the central line of the tongue. It's commonly seen in the population. Fissured tongue is a harmless condition and doesn't require any treatment. However, the cracks in the tongue can sometimes lead to food particles becoming trapped and cause bad breath. The exact cause of fissured tongue isn't known; genetic factors are thought to play an important role. This condition can also become more pronounced with age and can sometimes be seen alongside other conditions affecting the mouth. It's important for people with fissured tongue to pay attention to oral hygiene. Regular tooth brushing, along with cleaning the tongue with suitable products, is also necessary.
If you experience any discomfort or pain, it's recommended that you consult a specialist.
