An orthodontic flosser comprising an elongated handle and a head coupled to the handle at a vertical angle is disclosed. A first and second projection extend from the head for suspending floss, the first projection is sized for insertion of floss between a wire affixed to a tooth and the tooth. A source spool of fresh floss is configured to feed fresh floss incrementally into suspension between the first and second projections while a take-up bobbin is configured for taking up used floss and applying tension to the suspended floss. A button may be used for releasing the source spool to rotate, and for holding the source spool against rotation. The source spool and take-up bobbin may be disposed in separated chambers to reduce cross contamination. |
