| A hand-held instrument suitable for removing a wolf tooth from the upper jaw of a horse includes an elongated shank having a handle mounted on the rear end and provided with an extractor heat at the other forward end. The extractor head is preferably inclined at an angle to the axis of the shank to afford better leverage in prying and has a unique configuration terminating in a forward beveled cutting edge which permits the head to be slid between the wolf tooth and an adjacent tooth to loosen the root and pry the wolf tooth loose by applying a force to the handle outside the mouth of the animal with only two positions for the extractor head relative to the wolf tooth.
