Causes of black tongue coating in children

The color of the tongue coating is generally white or light red. Generally, the color change of the tongue coating is probably caused by eating pigmented foods. If the tongue coating turns black, it may be gastrointestinal disorder or high fever infection, or it may be caused by fungal infection. In this case, you need to see a doctor and get some medicine, and also pay attention to your eating habits. If you see a child's tongue coating is black, be sure to go to the hospital immediately.

The following are some common factors: First, infection with high fever: For some people, the black tongue coating disappears after the high fever subsides, but when the fever occurs for the second time, the black tongue coating reappears, proving that there is a certain relationship between fever and the appearance of black tongue coating. In addition, black tongue coating is also related to the duration of fever. It can be seen that the longer the fever duration, the more black tongue coating appears. In patients with black tongue coating, infection, high fever, toxic stimulation and other factors can cause the filiform papillae of the tongue to proliferate excessively, and then be stained black by microorganisms, and the brown-black keratinized cells unique to black tongue coating appear, making the tongue coating dry, yellow and burnt.

Second, gastrointestinal dysfunction: These symptoms of gastrointestinal dysfunction are mostly seen in patients with high fever, so intestinal dysfunction may be one of the symptoms of poisoning. Due to the stimulation of bacterial toxins, gastrointestinal dysfunction causes the pH value of oral saliva to decrease, which increases the adhesion between tongue cells and lengthens the keratin protrusions of the filiform papillae, making them easily stained black by microorganisms, forming black fur.

Third, fungal infection: Various bacteria, fungi and other microorganisms grow in the human mouth (including on the tongue coating). They usually restrict and promote each other, maintaining a certain balance, and do not pose any hindrance to human health.
