The present invention relates to dental wedges that may be used for creating space between adjacent teeth. In one form, the dental wedge includes an elongated body extending from an outer end to an opposite inner end. The body has a longitudinal intermediate wall, a longitudinal first side wall connected to the intermediate wall, and a longitudinal second side wall connected to the intermediate wall. The first side wall and the second side wall each flare away from the intermediate wall such that a first distal end of the first side wall and a second distal end of the second side wall are spaced apart creating an inverted generally V-shaped transverse section for the body. The body has a top surface formed by the intermediate wall, the first side wall and the second side wall. The body also has a bottom surface formed by the intermediate wall, the first side wall and the second side wall. The dental wedge includes a grasping section connected to the outer end of the body. A hollow region is defined by the bottom surface of the wedge and a first reference line extending from the first distal end of the first side wall to the second distal end of the second side wall. At least a first portion of the body comprises a first material that transmits light.
