A device for irrigating a canal during a root canal treatment or retreatment provides a fluid reservoir in fluid communication with at least one pump for delivering an irrigant under pressure. A hand-held wand has a proximal end for receiving the irrigant under pressure, permitted to flow through the wand head by an actuator. An irrigant delivery needle which affixed to the working end of the wand delivers irrigant through at least one irrigant dispersion orifice at a selected delivery angle and pressure. Aspirating means and/or shielding may optionally be provided.
