The Wonder Care Copper Tongue Cleaner is made of pure Alloy Free Elements. Tongue scraping is the simple practice of scraping your tongue before brushing your teeth. Brushing, flossing and even mouth wash are often not enough to remove harmful bacteria or build-up on the tongue. With a few simple scrapes, you can revitalize your tongue, teeth, and mouth, and protect the internal organs directly linked to tongue health. It not only kills bacteria in the mouth but also allows the healthy bacteria to get flourish. It is more effective in the removal of mucous, bacteria, and debris from the tongue than any toothbrush can. It also helps to prevent bad breath.
