Why there is a white coating on the tongue

As a rule, a white coating on the tongue testifies to any violations in the work of the human body. In a relatively healthy person, the tongue has a pinkish hue, sometimes with a small amount of pale plaque.
The tongue is a muscular organ whose surface is a mucous membrane. The cause of the appearance of a touch of a certain shade (white, yellow, black, etc.) is considered to be bacteria that accumulate in the oral cavity under the influence of this or that factor.
It is not always white on the tongue speaks of the presence of serious diseases of internal organs. For example, in the hot and dry season, the thickness of the plaque is much greater than in the cold months. This is due to the fact that when changing weather conditions, the supply of vitamins and trace elements to the body is impaired, which affects the appearance of the tongue. Such a coating has a rather thin texture, so there is no cause for concern. But if the thickness of the layer increases, it is necessary to closely monitor changes in the body and, if possible, consult a specialist for advice.
The second reason, when there is a white coating on the tongue, is the presence of an infectious disease. Of course, depending on the number and severity of the plaque, you can determine the course of the disease. For example, a thick layer indicates an active spread of the infection, therefore immediate treatment of the plaque in the language is required.
Often, a white coating on the tongue is a sign of disruption of the intestine. As a rule, this occurs when the body is poisoned or when constipation occurs. The structure of the plaque is a dense white layer. A plentiful covering of the oral cavity with a touch of white hue (including the tongue and the inner side of the cheeks) indicates a fungal disease, which is commonly called thrush. Very often this disease occurs in infants with insufficiently careful processing of personal items (nipple, bottle, mother's breast, pacifier). That is, the bacteria of the fungus enter the baby's mouth, resulting in their rapid multiplication and the formation of a white coating. Eliminating the cause and observing the rules of personal hygiene lead to an effective cure and relief from an unpleasant symptom.
If the plaque is expressed as white spots, then this is a symptom of the inflammatory process in the oral cavity. The most common cause of irritation of the mucous membrane is prolonged smoking or candidal stomatitis. Of course, the lack of treatment can lead to the fact that the malignant process begins.
When there is severe dryness in the mouth, a sharp smell of ammonia and a thick layer of white coating, it is necessary to examine the state of the kidneys. This is due to the fact that these are the most common symptoms of kidney failure, which are often accompanied by azotemia and uremia. Possible cause may be pancreatic disease.

Also there is a plaque in case of abnormalities of the stomach. The main treatment is to limit the consumption of fatty and spicy food. It is recommended to take activated charcoal, which neutralizes the negative effect of food on the walls of the stomach and digestive tract.
As a rule, the white coating in the throat or on the tongue disappears after eliminating the cause of its occurrence. First of all, you need to carefully care for the oral cavity and teeth. It is recommended that when brushing your teeth, do not forget about the surface of the tongue, on which there are a large number of bacteria that eat food leftovers. By eliminating food particles, you get rid of harmful microbes, which are a source of unpleasant odor and the formation of white plaque.
