GUM Expandable Dental Floss is designed and manufactured to help you remove plaque from hard-to-reach areas between teeth that have larger spaces, while also effectively cleaning more regular spaces between teeth. In use, floss expands to form a larger diameter chain that contacts more surface area around the gaps. Large gaps often occur due to gum recession and papilla loss, both consequences of periodontitis. GUM Expandable Floss is lightly lubricated with wax for ease of handling and insertion between teeth, and expands during use to clean tooth surfaces adjacent to larger spaces more effectively. The floss has a textured nylon construction that is gentler on the gums due to its wider diameter than regular fine floss. This is a specialized product to help make cleaning between teeth easier and more effective for people with irregular or large gaps between their teeth or those who find fine floss too narrow.
