Abstract
A dental cleaning assembly including a disposable dental tool including a main body tubular portion and a head portion disposed at right angles to the main body. A prophy cup is secured to a shaft projecting from the head portion so that the cup may be rotated to perform a tooth cleaning operation. A series of flexible bristles are secured to the head of the dental tool and extend forwardly therefrom in surrounding relation to the prophy cup so as to provide an anti-splatter shield for the cup to preclude splatter of toothpaste, saliva and blood. The bristles form an effective circumferential barrier around the prophy cup but yet allow complete freedom of movement of the prophy cup to perform the cleaning function and further allow potentially impacting paste to escape outwardly from the annular space between the prophy cup and the bristles to avoid impairment of the cleaning operation of the assembly.
