The present invention relates to a tooth cleaner. An injection nozzle for spraying water by a finishing cap is coupled to an upper end of a body divided into two parts and coupled to upper and lower ends by tightening a finishing cap. A seat portion on which a tube to be coupled to the spray nozzle coupled to the upper end is seated is formed inside the body. A protruding surface is formed at one side of the seat portion, and a water pressure control link mounted movably in a guide groove is mounted on a portion where the protruding surface is formed. Therefore, as the hydraulic pressure control link moves and the tube body located on the protruding surface is pressurized, locking and adjustment of the strength of water pressure are instantly and simultaneously performed while using the tooth cleaner, thereby facilitating the removal of foreign objects, tartar and bacteria, as well as gum massage and easily maintaining dental health by allowing people having weak teeth and gums to easily use the tooth cleaner according to the adjustment of spray intensity of cleansing water. In addition, while the hydraulic pressure control link is moved to regulate the hydraulic pressure, protrusions are formed at intervals in the guide groove to prevent movement. Concave/convex portions in which wavy patterns are continuous are formed on the surface of the body to form the assembly line of the body which is divided into two parts and is combined with each other, on the curved inner surface of the concave/convex portion so as not to be exposed to the outside, thereby improving appearance design.COPYRIGHT KIPO 2016본 발명은 두 개로 분리되어 상,하단에 마감캡의 조임으로 결합되는 몸체의 상단으로 마감캡에 의하여 물이 분사되는 분사노즐을 결합하고 몸체의 내부에는 상단으로 결합되는 분사노즐과 결합되는 튜브가 안착되는 안착부가 형성되고 상기 안착부의 어느 일측에는 돌출면을 형성하여 상기 돌출면이 형성된 부분에 가이드홈으로 이동가능하게 장착되는 수압조절링크를 장착하여 수압조절링크가 이동되면서 돌출면에 위치된 튜브체의 가압에 따라서 잠금은 물론 수압의 세기를 조절함으로써 치아세정기를 사용과 동시에 수압을 즉석에서 간단하게 조절하여 치아에 끼인 이물질과 치석과 세균 제거는 물론 잇몸마사지를 용이하게 할 수 있고, 세정수의 분사세기 조절에 따라서 치아와 잇몸이 약한 사람들도 용이하게 사
