Abstract: A self-contained dental flosser, with adjustable tension control and auto-tension locking mechanism, allows flosser to operate and advance the floss continuously in one direction by rotating the spool where the spool gears extend out of the main frame. Operation is as simple as rotating the spool by thumb and adjusting the tension by one finger, if necessary. The flosser contains a total of three parts: 1) an elongated body with a lid containing two stabilizing cylinders, a locking mechanism, two prongs set on an angle for effortless flossing, hollow axles in separate compartments, and a separation wall, 2) one spool for holding the clean floss and 3) the second spool for holding the used floss.
