Cracks in the tongue may be caused by furrowed tongue, tongue atrophic disease, vitamin deficiency and so on.
1. furrowed tongue: the etiology of furrowed tongue is still unclear, it is generally considered to be caused by congenital tongue development abnormality, which is related to genetic factors; there are also regional episodes characterized by the current consideration of genetic factors and environmental factors play a joint role in the results.
2. Tongue atrophic disease: the epithelial layer of the tongue loses its normal structure, part of the papillae become flat and fused, and part of it atrophies and breaks off, thus forming cracks.
3. Vitamin deficiency: usually eat less green vegetables and fruits, resulting in vitamin deficiency, which may also lead to cracks on the tongue.
Cracks on the tongue should not be treated blindly by yourself, but go to the hospital in time, after clarifying the cause of the disease and actively treating it, so as not to aggravate the symptoms.
