An apparatus for removing crowns from teeth wherein the apparatus is a plier-like instrument having upper and lower opposing jaw portions with the lower jaw including a tapered and pointed member for engaging the lower margin of a crown and wherein the upper jaw supports an axially offset and rotatable pin member which may be adjustably positioned so as to apply pressure over a cusp and along the elongated axis of a tooth through a predrilled opening in the upper portion of a crown so that opposing pressure may be applied by the upper and lower jaw portions of the instrument to lift and separate a crown from a tooth.
