I got hairy tongue when I followed the directions of the person who pierced my
tongue. He said to rinse with
listerine after eating, drinking, smoking,..... And I did. When my tongue started getting white, I thought it was just being dried out from the Listerine, then I thought infection, so I went to my dentist. Hairy Tongue, YUCK! it *****, I dont even feel comfortable kissing my husband, unless I just scraped it off. I cringe just writing about it.
