The Tongue Cleaner is used to scrape the tongue in order to help reduce bacteria, improve breath, and increase oral hygiene. Scientific studies have shown that the primary source of bad breath is the tongue. During sleep the tongue accumulates an unpleasant film of bacteria and other compounds. This is why after brushing your teeth, fresh breath is difficult to maintain.
