Apparatus and methods to hold and manipulate dental floss for the removal of plaque and food particles from teeth surfaces. The invention comprises: an elongated handle which may house, contain, and dispense a supply of dental floss; a stationary tong which does not generally move with respect to the handle; a pivotal tong which can be pivoted about a pivot point; means for securing the pivotal tong to the handle to selectively adjust the distance between terminal ends of the stationary tong and the pivotal tong; and means for anchoring the dental floss to the terminal ends of the stationary and pivotal tongs, the dental floss being positioned to span the distance and be pulled taut between the terminal ends of the tongs. Means for guiding the length of dental floss along the stationary and pivotal tongs and/or means for cutting the dental floss may also be provided.
