A handheld orthodontic tool includes a housing, electric motor, and a probe configured to engage a tooth. An operator applies manual pressure to the tooth with the probe, and the electric motor activates to vibrate the tooth through the probe. The orthodontic tool enables accelerating individual tooth or a group of teeth during orthodontic treatment to reach differential tooth movement speed, which will shorten the treatment time and reduce side effects including root resorption and anchorage loss.
