Abstract: A multi-tooth-surface brushing device for improving cleaning capacity by maximizing bristle contact with the lingual, the vestibular and the occlusal tooth surfaces simultaneously throughout the entire brushing process.

Abstract: A tooth cleaning device having (a) a tooth cleaning head, including: (i) a housing with sides that straddle the tooth along both long faces and defining a longitudinal axis extending between the sides thereof and along the long faces; (ii) gears affixed along respective inner surfaces of the sides of the housing; (iii) tooth cleaning elements affixed along the inner side of the gears and being operatively spaced apart from one another, along the longitudinal axis of the tooth cleaning head, to form a gap therebetween; and (iv) a drive mechanism including: a drive shaft affixed to the inner surfaces of the sides of the housing and spanning the housing, a drive wheel connected to the drive shaft, and transfer gears affixed near ends of the drive shaft and aligned with the gears; and (b) a handle connected to the tooth cleaning head, wherein as the tooth cleaning device travels along a row of teeth, the drive wheel rotates along the biting surface of the teeth, thereby rotating the drive shaft and the transfer g
