A non-sterile device designed to scrape the upper surface of the tongue to promote oral hygiene (e.g., to remove plaque, food debris, and bacteria, and to prevent bad breath). It is normally available [non-prescription] over-the-counter (OTC). It is typically made of plastic and is available in a variety of designs (e.g., a U-shaped band or a T-shaped instrument), and has a scraping ridge that is manually pulled over the surface of the tongue. This is a single-use device.
