Tongue cleaner for less gagging: Peter Ferrer Dual 5th Gen
Peter Ferrer Dual 5th Generation Tongue Cleaner is an oral-care tool tested in Korea. After using it daily for more than a week, I found its slim head made cleaning the back of my tongue feel less gag-inducing and easy to rinse under water. Verdict: a strong pick for anyone who gave up tongue cleaning because of gagging.
