ABSTRACT:
An extraction device for extracting some or all of a tooth from a patient, such as the root of the tooth. One embodiment of the device includes an extraction bit having helical windings without a linear core portion separate from the windings, and in that manner is distinguishable from a common screw. The extraction bit may include a partial-spiral flute or groove formed in a tip thereof. A lockable and releaseable hand piece for attaching to the extraction bit provides leverage to the user for dislodging the tooth root, and is reversible in its attachment position to the extraction bit.
