Floss that whitens! Recommend the floss patients will actually want to use. What a bright idea! The first floss that is clinically proven to remove stains between teeth. It’s a brilliant way to encourage compliance. In fact, in home-usage studies, 86% of patients using new Johnson & Johnson REACH® Whitening Floss said they BEFORE would purchase it. This unique floss is a shred-resistant, easy-to-slide, silica-coated yarn designed to gently polish away stains. Johnson & Johnson REACH® Whitening Floss is definitely an idea whose time has come.
