The bacteria in your tongue isn't gonna scrape itself, so you need something with hard ridges to do the nasty work for you. Tongue scrapers have been around for almost a century, but this one is the coolest and most effective one yet. Some scrapers out there are metal - but we vowed to never put metal in our mouths after braces. Some are long rods that make you gag as they go into your mouth. This tongue scraper is the perfect one that is gag-proof and effectively scrapes your tongue.
