An electric device which removes supragingival and sub-gingival plaque and undesirable debris from the interproximal surfaces between teeth is described. This device utilizes a combination of sonic energy and dental floss which is secured between two tines, the tines being part of a flexible fork which is removable from a powered handle which contains batteries and an electric motor.
