This invention relates -to sprays and parcavities in the teeth and-frombetween the 19 teeth and cheeks." As the nervesof the teeth are very sensitive to changes of temperature it is necessary to use a washing -01 flushing liquid which has been heated to approxi; mately' normal body temperature. Accordingto some of the older practices hand syringes which were filled when necessary from open vessels containing heated water were used. This method was not, entirely satisfactory as it was difficult to maintain the water in the open vessels atuniform temperatures, andthefilling of the syringes satisfactorily required .considerable time; Also, considerable time was required for maintain ing a supply of fresh water in thevessels, and since the syringe and water container were separate articles, it was frequently the case that one orthe other was not immediate ly available when needed.

ed water from the container have been provided. In the usual form of such apparatus the flow of water is controlled entirely by a small valve positioned in the spray head, and the spray head when not in useis placed in a rack or holder on some part of the apparatus stand or support. Owing to the fact that the valve in the spray head must be of the type which can be quickly opened and closed, "it has been found to :be diflicult if not impossible H I in'use. Since it 1 is highly desirable that dental to provide such a valve which can withstand the pressure of the usual water line without leaking. Consequently there may be a con 'tinual dr-i-p from the spray head to the floor "when'it-i's supportedin its inoperative posi-' 65 tionon the stand or support. found,also, that even when there is no leak- It has been age from the spray head due to pressure from the water line, there is a slight drip from the discharge endof thespray head for a short time after ithas been used. In some cases containers have beenplaced on the floor of theoperating room to catchthe drip and in other cases it has-been allowed to fallupon the floor. Ineither case the result achieved is unsightly; I

A secondnipple 23 extends through an opening inthe bottom wall of the passage17 and it is-so positioned and of such a length that it normally extends within the member 10 to a point adjacent the bottom thereof. Cold water, as it enters the container, is thus conducted toits natural place at the bottom.

'A nipple 24 provides means for attaching the flexible-tube'12 to the device in such a manner that it communicates with the out let passage 20. An opening 25 provides meansof communication between the member 10 and the passage 20. An annular ridge 26 surrounding the opening 25 provides a seat for a valve 27'Wh1ch1s mounted in an opening in the upper wall of the passage 20.
