GUM® Deep Clean Expanding® Floss expands during use to remove 3X more plaque than the leading Deep Clean foss*. Promote healthy gums, cleaner teeth, and fresher breath with GUM® Deep Clean Expanding® Floss. Our woven floss starts out as a soft, textured thread that slides easily into interdental spaces. Once in use, it expands to clean a larger surface area between the teeth and beneath the gum line. Our unflavored dental floss makes it easy to remove plaque from hard-to-reach areas that are missed by brushing alone - even for those with tight teeth. With Deep Clean Dental Floss, maintaining your freshest, most confident smile has never been easier.
