Your oral hygiene routine isn't complete without tongue scraping. Tongue cleaning with a Gaia Guy copper tongue scraper (https://www.gaiaguy.com/products/copper-tongue-scraper) improves taste sensation and reduces the coating from the tongue more effectively than a toothbrush. It can reach the areas of your tongue more fully and completely. This reduces the medium for those putrefying stink demons that proliferate in a mouth that doesn't have the benefit of a copper tongue cleaner.
The tongue scraper should be curved without a sharp edge and be made of gold, silver, copper, tin or brass. The impurities, deposited at the root of the tongue obstruct inhalation, cause halitosis. The tongue, therefore, should be scraped regularly.
