A tongue cleaner removes more mucous, bacteria and debris from the tongue than anything else and with terrific ease and efficiency. This has been proved through the experience of oriental civilizations that have used tongue cleaners for centuries to have the lowest incidence of tongue diseases & disorders. Made with 100% pure & finest Copper. Copper has been known to naturally fight bacteria and plaque for centuries. Dental Research indicates that the surface of the tongue is a major source of bad breath. Most bad breath originates from the bacteria on the tongue-not from the stomach, not from something eaten, but from the back of the tongue, a fertile breeding ground for the offensive foul odor-causing germs. Tongue Cleaning (such as with this tongue scraper) is clinically proven to be the single most effective way to reduce bad breath.
