Dr. Tung's Stainless Steel Tongue Cleaner
This is so much nicer than those cheap plastic tongue scrapers, and is durable enough to throw in the silverware section of your dishwasher.
If you haven't used a tongue scraper, you need to start. This is an essential oral care tool. If you have a hard time drinking enough water because after a while you are over the funky taste in your mouth. If you have chronic bad breath, if you have a "fuzzy" tongue when you wake up in the morning, you need this in your life.
