Bad breath is commonly caused by bacteria in the mouth. So this bacteria can either be between the teeth or at the back of the tongue. So to clean between the teeth, of course, it’s floss. However, to clean the back of the tongue, we recommend using a tongue scrape scraper, which is an instrument made of plastic. And it’s essentially brushing the bacteria off the tongue. You can purchase tongue scrapers from us. Otherwise, they’re a little bit difficult to find in pharmacies. But there are some that have them otherwise online.
