  • Patent number: 7128575
    Abstract: A tooth elevator designed to minimize risk of injury to a patient's mouth or adjacent teeth during tooth extraction is described. The elevator has mating side members, a handle portion and a mating jaw portion. As force is applied to the handle portions, the jaw portions are urged together on either side of a molar to be extracted. Inward curving side members disjoint the tooth upwardly while an angled front face simultaneously moves the tooth back, loosening it for extraction. A variation of the tooth elevator has a downward angled offset that allows a practitioner to easily position the elevator in a patient's mouth without the discomfort of raising the elbow of the grasping hand. The handle portions may also have non-slip features.
