A method and device () for dynamically checking the teeth of a part () including a first motorized spindle (), supporting the part () to be checked, is controlled by a first encoder (), and a second motorized spindle (), supporting a master pinion (), is controlled by a second encoder (). The two spindles () are parallel and separated from one another with the master pinion () meshing with the part () to be checked. The master pinion () has a small thickness, compared to the part () to be checked, and the spindle () is mounted on a first carriage () which is movable in order to move the master pinion () along the profile of the teeth of the part () to be checked. This method and device allows characterizing both the radial defects and the angular defects of the teeth, and these defects being differentiated.
