Simple home remedies for a coated tongue can be incorporated into your daily routine to aid in the continual removal of the coating. The coating is intertwined with the surface of the tongue and if left unattended can create bad breath. Gargling will not remove the coating but can help flush away the debris after it is loosened. Smoking, the release of toxins by the body and low fiber intake may cause tongue coating.
A coated tongue may contain bacteria. Use a toothbrush or a store bought tongue scraper to reach the whole surface of the tongue and rinse away the bacteria with mouth wash or water. Make scraping the tongue part of your morning routine to keep your mouth clean. Metal or plastic spoons can also be used to remove the coating. Begin at the back of the tongue with the spoon turned face down and then pull forward. Vigorously rubbing the tongue across the teeth also loosens the bacteria. Just rinse the mouth out with water afterward.
Eat A Remedy
Stimulating the flow of saliva can help dislodge the coating from the tongue and freshen the breath at the same time. Eating can actually aid the process—try an orange. Oranges contain citric acid which stimulates the salivary glands, helping to wash away bacteria and the coating. Rinse your mouth after eating the orange or any food, to help flush the dislodged matter away. A cup of mint tea or chewing on a sprig of parsley will help with the bad breath that often accompanies a coated tongue.
The Mayo Clinic suggests a homemade scrubbing recipe to remove the coating. Mix one part hydrogen peroxide and five parts water (i.e. one tablespoon of hydrogen peroxide to five tablespoons of water). Dip a toothbrush into the mixture and gently brush the tongue. It's never a good idea to swallow hydrogen peroxide. Rinse with water after using the scrubbing recipe. Baking soda and water is another scrubbing recipe to work with. Baking soda will refresh the mouth. Try mixing in a teaspoon of fresh lemon juice, not reconstituted lemon juice.
