A dental floss dispensing unit includes a housing, a supply spool, and a metering element. The supply spool is coupled to the housing and has a length of floss wound thereabout. The length of floss has a free end extending from the housing and a plurality of alternating and distinct first and second floss segments. The metering element engages the length of floss and provides resistance to removal of the length of floss from the housing. A magnitude of the resistance changes as each floss segment moves into engagement with the metering element, thereby providing a tactilely detectable indication to the user that one of the first or second segments is emerging from the housing. The dispensing unit is configured to allow the supply spool to be manually rotated without manipulation (e.g., disassembly) of the housing for rewinding floss onto the spool.

Dispenser for multi-texture floss

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.

Multi-texture floss and methods of manufacturing multi-texture floss

A dental floss dispensing unit comprising a housing and a supply spool coupled to the housing and having a length of floss wound thereabout. The supply spool being adjustable between a locked position, where the supply spool is fixed with respect to the housing, and an unlocked position, where the supply spool is free to rotate with respect to the housing.
