Tongue should be cleaned every day, regardless of whether scurf appeared or not. This should be done after you've brushed your teeth and rinsed your mouth. Use the scraper every morning and evening. It is especially important to clean the tongue before bedtime, becousse during the sleep the decomposition of food residues (source odor) in the mouth is the most intense. Scraping your tongue must be smooth with light movements from the back to the very tip of it, without applying excessive force. Don't touch the root of the tongue to avoid discomfort.
