how to treat coating on the tongue brown

How does it appear?

The surface of the tongue is rough because it has small taste buds on it. If a person is healthy, they are of white color. The tongue itself has to be pink.

During the meal, the food particles stuck between those taste buds. As the result, a favorable environment for the development of a variety of bacteria is created. This process looks like a plaque of different shades.

Type of food can affect the color of a tongue. For example, if you drink coffee or eat chocolate, it becomes brown. After cleaning the mouth, it should go away.

If after cleaning the tongue brown color does not go away or comes back after a time, you should look for the cause of this phenomenon.

Doctor, examining the mouth, pays attention to the tongue color and the thickness of the plaque:

  • If the layers are thin, it means that a person begins to develop a viral disease.
  • Thicker formation suggests that the patient has a chronic illness.


It may appear as a result of the use of colored food or as a result of serious chronic diseases.

Typically, the brown plague speaks of the digestive system disorders. The more intense it is, the more acute stage of the disease is.

If these symptoms are ignored, then the coating darkens, and the patient’s condition deteriorates. There are sores in the mouth and increased body temperature.

Its origin could mean the development of the same diseases as among adults. On examination, the child’s doctor first determines the thickness of the layers and its localization:

  • Tip of the tongue. This means that the child needs to check the bronchi or the lungs.
  • Symmetrical patches. May indicate the pneumonia development.
  • Centre of the tongue. This localization suggests that a child has problems with the gastrointestinal tract.

Brown staining occurs as a result of receiving the dye products. Quite often it happens when a child is introduced to a new food.
