A dental delivery tool sized and configured to deliver a dental composition into a dental preparation includes: (A) a hollow body configured to deliver a dental composition therefrom; and (B) a plurality of fibers coupled to at least a portion of the hollow body. A portion of the fibers extend a length "L" distally beyond the rim of the hollow body. A portion of the fibers are coupled along the wall a distance "D" proximally with respect to the rim. The distance "D" is at least about two and one half times greater than the length "L". Employing the tool, which may be a delivery tip, for example, the interior walls of a dental preparation may be conveniently brushed or cleaned during a procedure in which a dental composition is delivered using the dental delivery tool.

A dental delivery tool as recited in claim 14, wherein at least a portion of the fibers extending the length "L" distally beyond the rim of the hollow body extend substantially perpendicularly from a face of the rim. 16. A dental delivery tool as recited in claim 14, wherein at least a portion of the fibers coupled along the wall of the hollow body extend substantially perpendicularly from the wall. 17. A dental delivery tool as recited in claim 14, further comprising coupling means for coupling the hollow body to a syringe. 18. A dental delivery tool as recited in claim 14, wherein the fibers are deposited onto the hollow body by electrostatic flocking. 19.
