Abstract: A tool for seating dental aligners is disclosed. The tool includes a longitudinally extending body that includes a handle positioned proximate a distal end of the body. A claw portion defined by a facial finger and a bite finger extends towards a proximal end of the body. The facial finger is adapted to transfer force applied using the handle portion to a facial surface of a dental aligner positioned along one of the upper teeth and the lower teeth of a user. The bite finger is adapted for compression between the mandible and maxilla of the user for applying force to an incisal-occlusal surface of the dental aligner. The bite finger and the facial finger are shaped and positioned relative to one another to allow concurrent application of force to the dental aligner for seating the dental aligner on the upper or the lower teeth of the user.
