A flossing device has an internal floss feed in which floss is advanced from a storage chamber in the handle of the device, through feed gears, to a pair of spaced apart tines. The tines are configured to fit into the mouth such that the floss may be easily worked between the teeth. Spent floss is returned through the return gears, the return gears having a greater diameter than the feed gear, thus ensuring the floss remains taut between the tines, to an integral cutter whereby it may be cut off and discarded. In a second embodiment, the flossing head has a vibratory device to aid in the flossing action.
