Ans.Yes it is an important part of the oral hygiene routine. It holds the same importance as burnishing your teeth. The tongue is an important part of the digestive system and the bacteria on tongue can cause bad breath and problems in digestive system. You can either use the tongue scraper, toothbrush or mouth rinse, to clean your tongue. This daily oral practice gets rid of the bacteria and food particles stuck on the tongue. If it is not removed, the tongue looks discoloured and hairy. An oral infection ‘oral thrush’ or yeast infection might develop. Cleaning of tongue once or twice daily, may help to reduce bad breath and chances of other infections. But be gentle and careful while scrapping, you may damage the taste buds by overdoing the cleaning.
