    Abstract: In one embodiment the Dental Wedge is formed by two flexible members defined as a gingival member and an occlusal member. The gingival member is C-shaped between its ends and generally triangular shaped in cross section. It has an outer side which gradually increases in width from a pointed end to a wider end. The occlusal member is curved and is also generally triangular shaped in cross section. Connectors are provided for connecting the two ends of the two members together to form a closed loop wedge. The gingival member may be inserted partially through the gingival embrasure of two adjacent teeth from its pointed end with its outer side facing the gum.
