Your tongue can tell many tales.Each part of your tongue is said to correspond to an organ in your body.A coating on your tongue is a sign of accumulated toxins - and hence scraping off some of those toxins on a daily basis makes complete sense.
Copper has been used for centuries as a bacteria resistant metal.Studies show that Copper not only seems to be toxic to the bad bacteria but it also provides important enzymes that are needed for the healthy microbes in the mouth to survive.
A copper tongue scraper also resists bacterial accumulation while not in use, offering you protection long after its use.
