"IMPROVED METHOD AND APPARATUS FOR EXTRACTING TEETH" ABSTRACT OF THE DISCLOSURE This invention relates to an improved tooth elevator characterized by a bit terminating in a blade having a generally S- shaped or reverse S-shaped cross section. The invention also encompasses the novel method of extracting at least one of a pair of adjacent teeth with an elevator having an S-shaped or reverse S-shaped tip which comprises. inserting the bit with its axis essentially horizontal in between the teeth to be extracted and rotating said bit about its axis in a direction such that a remote sharpened edge of the S-curve engages one of said teeth at a point spaced from the gum line defining a fulcrum about which the adjacent sharpened edge of the S-curve pivots into prying engagement with the other tooth of the pair nearer said gum line so as to lift the latter out of its socket.
