The dental wedge (10) includes a generally tetrahedral body having a central longitudinal apex (26) flanked by a pair of resilient side walls (22, 24), connecting a narrow distal point (14) and a wider proximal end (12), and having an open underside (18) opposite thereto, as well as a protuberance (28) extending axially from the proximal end (12) and adapted for gripping by a dental implement. |
