Never used a tongue “scraper” in my life and yet:

1. Breath fresher than alpine air
2. Supremely acute taste
3. Tongue coated *just right*
4. Food particles never stick on my tongue, as if my tongue has a dwr or teflon coating

All of these statements have been independently verified by NASA, CERN, and PBOC.

NASA, CERN, and PBOC verifying the benefits of using a tongue scraper? That's some serious scientific validation right there. Maybe it's time to invest in one and experience the wonders of fresher breath and a super-coated tongue!
