Abstract: An apparatus for holding dental floss in tension, comprises of two components that form two sets of pivoted arms that holds the floss in tension between them; a means that host a repository of floss, such as a spool for example; and a means to anchor the dental floss that also hosts a sharp object to sever the excessive floss segment. Angular movement happens when the said two pivoted components move close to and away from each other. The said angular movement is then transformed to the horizontal sliding movement of a separate module which in turn locks the said repository of the spool, stopping it from dispensing more floss; changes the overall body length of the said apparatus; and drive a means which anchor and grip tight the floss. Together the locked repository, gripping anchor, and changing of the device length tighten the floss being held between the said two sets of the pivoted arms.
