A dental wedge and forming device utilizing a unitary body having a pair of wings which are intended to lie against the outer surfaces of adjacent teeth, either on the lingual or buccal region of the teeth. A curved nose is constructed to extend between the adjacent teeth and includes a flat side and an opposite radiused side. A pair of the devices are nested in opposition in order to hold a dental matrix band in place about a prepared tooth, thus allowing a dental practitioner to practice proper biomimetic restorative techniques.
