About Tongue Scraper Guide
We research and test tongue scrapers using measurable criteria so you can buy with confidence.
How we test
We score every scraper on three criteria. Coating removal: we measure the percentage of a standardized test coating removed per pass compared to Dr. Tung's baseline. Flex and comfort: we rate the arm flex on a 1-10 scale and record gag reflex observations from 5 testers. Durability: we bend-test handles and inspect scraping edges after 30 and 90 days of daily use.
We also consult dental hygiene research when it is available. The FAQ sections on our guide pages cite specific studies where relevant.
