Can someone tell me why dental floss is so expensive? It’s a piece of string. Does that waxy coating really account for the $4.49 price for Glide Comfort Plus? Sure, you can get some $1.99 brand, but it’s like flossing with thread. Seriously, dentists, if you want us to floss every day—and I know you do because I get the lecture every six months— then you should pressure Crest and others to make its flimsy string affordable.
