An oral hygiene system comprising a hand-held instrument attached to a mobile cart by an accessory hose. The instrument has two main components: a pistol-grip hand-piece, and an individualized patient attachment. The pistol-grip hand-piece includes irrigation, suction and brush speed controls, as well as an adjustable swivel piece for changing the orientation of the attachment. Inside the hand-piece is a light source with fiberoptic tubing which channels light to the attachment, and a two speed electric motor which powers a rotary brush. The attachment itself is a relatively inexpensive component, one of which is assigned to each patient. It is cylindrical with a right angle curve at the distal end, to which is attached a disposable rotary brush. An orifice for the suction, and irrigation portal, and the fiberoptic lighting are also located at the distal end of the attachment. The proximal end of the attachment attaches to the hand-piece at the swivel piece and a disposable, clear, plastic shield attaches to the attachment mechanism to protect the hand-piece from splatters.
