Rust proof, plastic free, copper tongue cleaner. The ancient Ayurvedic recommendation of tongue scraping is one that is often overlooked. There are many benefits to this daily practice for oral health, as well as overall physical and mental, health. Since the tongue and oral cavity are gateways between your mind-body system and the outside environment, maintaining the health of this vital organ is critical to general well-being. A tongue scraper is the best way to remove bacteria that can cause bad breath. Tongue cleansing also helps improve taste, remove the coating on the tongue, slow the growth of plaque and improve digestive health.
