Tongue cleaning is an ancient Ayurvedic practice and can be easily combined with other oral hygiene practices. The scraper is traditionally made of copper but many people today prefer stainless steel. Regular tongue scraping can slow the growth of odor causing bacteria as well as reduce the level of bacteria in the mouth. According to the Charaka Samhita, regular tongue cleaning also improves respiration. If one is doing oil pulling, then tongue scraping can be done before swishing with oil. After each procedure, it would be wise to rinse the mouth several times with warm water. A drop of essential oil can be added to the water or one can use a very small amount of apple cider vinegar. These rinses can performed several times a day. Alternatively, one can use a mouthwash or herbal rinse after scraping the tongue and swishing with oil.
