A standardized furniture unit including at least two substantially vertical side panels, bracing extending between the side panels, the intersection of the bracing and the side panels defining interior corners, and a bracket disposed in at least one interior corner, the bracket having an upper mounting plate and a lower mounting plate, the upper mounting plate having means for connecting a caster to the upper mounting plate, the lower mounting plate having means for connecting a leveler to the lower mounting plate, and at least one of a leveler connected to the lower mounting plate and a caster connected to the upper mounting plate. in turn, supporting said brush head to undergo movement along an endless path of revolution having an axis of revolution extending substantially parallel to said brushing plane of said brush head such that said brushing plane is maintained in a given orientation relative to a surface of a set of teeth throughout movement of said brush head along the endless path of revolution, said guide arrangement including (i) forward and rearward pairs of upright guide posts spaced apart and extending parallel to one another, and (ii) a plurality of sleeves each mounted over and slidable along one of said guide posts. 2. The toothbrush of claim 1 wherein said brush head carries bristles defining said brushing plane. 3. The toothbrush of claim 1 further comprising: a drive mechanism having a rotary crank rotatably connected to said brush head such that in response to rotation of said rotary crank said brush head is moved along the endless path of revolution. 4. The toothbrush of claim 3 wherein said brush head includes: a head portion carrying bristles which define said brushing plane; and a plate portion rotatably supporting said head portion such that said head portion is capable of undergoing rotation relative to said plate portion as both said head and plate portions undergo movement along the endless path of revolution. 5. The toothbrush of claim 4 further comprising: a linkage pivotally connected to said handle and said head and plate portions of said brush head such that said head portion in response to rotation of said rotary crank is caused to rotate relative to said plate portion and move along an oscillatory path as said head and plate portions of said brush head are moved together along the endless path of revolution. 6. The toothbrush of claim 1 wherein said guide arrangement further includes forward and rearward slide rods spaced apart and extending transversely to said respective forward and rearward pairs of said guide posts and between and attached to said sleeves on said pairs of guide posts. 7. The toothbrush of claim 6 wherein said brush head is slidably supported on said slide rods so as to be capable of concurrently undergoing horizontal movement along said slide rods toward and away from said guide posts and sleeves and vertical movement with said slide rods and sleeves along said guide posts and thereby revolving movement about the endless path of revolution. 8. The toothbrush of claim 7 further comprising: a drive mechanism having a rotary crank rotatably connected to said brush head such that in response to rotation of said rotary crank said brush head is moved along the endless path of revolution.
