Abstract

A multi-texture dental floss includes distinct and alternating segments having varying textures, including smooth segments and textured segments. The smooth segments are more easily inserted into the spaces between teeth, while the textured segments more effectively remove plaque and other debris therefrom. Methods of making the multi-texture floss are also disclosed, including methods that allow the floss to be made as a continuous thread having a plurality of alternating segments, such that the floss can be wound onto a spool for storage and dispensing.
