What color of tongue coating is normal?

Healthy people's tongue coating should be pink, and the surface of the tongue looks very refreshing, which will not give people the feeling of hypertrophy. There are no bite marks on the tongue, and there will be no bad breath when exhaling. If your tongue looks like this, it means that your body is well maintained and you don't need to worry too much about health problems.

If the tongue coating is obviously white, but only a thin layer, it feels like it grew on the tongue from the beginning. If it happens once or twice occasionally, it doesn't explain the physiological problems. Just pay more attention to the cleanliness of the mouth. If this happens continuously, it may be because there is more internal heat in the body, which is a typical phenomenon of getting angry. Always pay attention to drinking more water. After the internal heat disappears, the white coating on the tongue will slowly disappear.
