1. A hand-held dental tool, comprising:
a generally straight handle portion having a proximal end and a distal end;
a generally curved neck portion integral with the handle portion and having a proximal end and a distal end, the proximal end of the neck portion being connected to the distal end of the handle portion such that the neck portion extends generally downward with respect to the handle portion;
a retractor integrally connected to the neck portion and having a proximal end extending from a first point on the neck portion which is located approximately in a middle region of the longitudinal extent of the neck portion, the retractor extending to and having a distal end which is located distally further than the distal end of the neck portion, the retractor having a first width at the first point which is substantially equivalent to a width of the neck portion, and having a second width at the distal end which is greater than the width of the neck portion, the retractor curving downward and laterally as it extends distally to the distal end, and curving inward and proximally at the distal end to thereby create a concave shape in two intersecting directions, the distal end of the retractor being continuous and wider than the neck portion and extending without any interruption along its width;
said handle portion and said neck portion being substantially hollow to thereby create a continuous fluid passageway extending from the proximal end of said handle portion to the distal end of said neck portion, the fluid passageway at its distal end being supported by the retractor.
