CA 2638068
There are provided a device and a method for cleaning teeth. The device comprises a brush, a shaft connected to the brush, a neck surrounding the shaft along a substantial portion of the length of the shaft, and a controller coupled to the shaft at the end of the shaft opposite the brush, the controller being mounted at the base of the neck so as to be movable between a first position that extends the brush away from the neck, and a second position that retracts the brush towards the neck. The method comprises inserting, between adjacent teeth, a device having a brush, a controller and a handle, the controller for effecting movement of the brush in a direction generally perpendicular to the handle, and keeping the handle generally stationary while moving the controller up and down to move the brush along front-to-back and back-to- front paths between the adjacent teeth. Moving the controller may occur via pressure from a user's finger, or via force from a motor in the device. In some cases, the method includes vibrating the brush while it is moved along the front-to-back and back-to-front paths between the adjacent teeth.
