Textured and/or patterned dental floss and methods for making the same are disclosed. In accordance with the embodiments of the invention dental floss comprises a ribbon structure with patterned features. The patterned features are periodically or spatially arranged along the ribbon structure of the floss and are preferably protruding, receding, textured, abrasive and/or porosus, such as to aid cleaning of inter-proximal regions of the teeth and gums and/or aid in the application of a medication or antiseptic to the inter-proximal regions of teeth and gum while flossing. In accordance with the method of the invention, the dental floss is made by forming textured and/or patterned sheet using an extrusion process, a co-extrusion process, a hot-melt process, a laminating process, an embossing process or any combination thereof. The patterned sheets are then converted into elongated ribbons with patterned features.
