If you have a white - coated tongue, here are some ways to deal with it.
First, maintain good oral hygiene. Brush your tongue gently with a toothbrush or a tongue scraper when you brush your teeth. This can help remove the bacteria and debris that cause the white coating.
Drinking plenty of water is also beneficial. Water can help wash away the substances that lead to the white - coated tongue and keep your mouth moist.
If the white coating is caused by indigestion, you can adjust your diet. Eat more fruits, vegetables and foods rich in fiber to promote good digestion. Avoid over - eating greasy and spicy foods. In some cases, traditional Chinese medicine believes that certain herbal teas like those with chrysanthemum or mint can help clear the internal heat and relieve the white - coated tongue caused by internal factors.
