The present invention provides a novel dental flossing device (1), which is adapted to be inserted entirely into an oral cavity of the user. The flossing device (1) comprises a floss string (10) and at least two manipulation members (21), which are connected by the string (10) for control thereof. The manipulation members (21) are adapted to be guided by oral muscles, particularly the tongue, of the user, whereby the floss string (10) may be guided by tongue via the manipulation members (21) without introducing fingers to said oral cavity.
