This is a fissured tongue, showing multiple small furrows or grooves on the dorsal (top) surface of the tongue. These fissures can be shallow or deep, single or multiple. Often there is a prominent fissure in the center of the tongue. A fissured tongue is seen in about 2-5% of the population. The tongue shows large fissures that look painful but are pretty painless, although can experience sensitivity and pain with orange juice, spicy food etc. The cause is not known and it is usually observed as an incidental finding on a routine dental examination. Fissured tongue is a harmless condition usually with no associated symptoms. No treatment is necessary except to encourage good oral hygiene including brushing the top surface of the tongue to remove any food debris from the fissures. Cleansing of the tongue helps prevent irritation and possible bad breath that may occur from food getting trapped in the grooves. Photo by @ahmad_m._kurdi
Itβs asymptomatic, meaning it doesnβt hurt. But it probably feels weird to press your tongue to the roof of your mouth
Its called lingua plicata/ fissured tongue/ scortal tongue in dentistry. It is a feature of MR syndrome
My tongue looks like that. Doesn't cause any problems at all. I've also got a skin tag in the middle.
