An electricity-supplying and water-supplying cord for use in dental surgery is made of a bendable, resilient member and has at least one hole for inserting electricity-supplying wires therethrough and one hole for inserting a water-supplying hose therein. The cord is provided with a straight rift along the axis of the hole for use in inserting the water-supplying hose. Further, a hose-inserting tool provides for inserting the resilient water-suppling hose into the hole which is formed in the abovementioned electricity-supplying and water-supplying cord.
