Yellow coating on the tongue of a child25.05.2022
The color, density and localization of plaque in the child’s tongue provides information about many processes occurring in his body. If the plaque is whitish, odorless and easily removed with a cotton swab or toothbrush, there is no reason to worry. This plaque is formed by the accumulation of saliva, epithelial cells, food debris and microorganisms living in the oral cavity. Usually such a plaque can be seen on the child’s tongue in the morning, after sleep. To remove it, oral hygiene and food intake are sufficient.
Why plaque on the tongue turns yellow
If during the day the child did not eat foods containing natural dyes (vegetables and fruits of bright orange color, frozen ice, lollipops, etc.), as well as carbonated drinks containing chemical dyes, then among the factors causing yellowing of plaque on the tongue , the following can be distinguished.
Diseases of the gastrointestinal tract (GIT)
A white-yellow coating may indicate gastritis, colitis, or a stomach ulcer. The child complains of abdominal pain, nausea, heartburn, loss of appetite.
Diseases of the liver, gallbladder and biliary tract
