PURPOSE: An injecting system of a fixed amount of fluorine solution to prevent tooth decay is provided to prevent a pipe from becoming rusty when injecting undiluted solution by supplying fluorine solution diluted through the filtered supplied water with a circulation pump. CONSTITUTION: An injecting system of a fixed amount of fluorine solution to prevent tooth decay comprises several storage tanks(100); a fixed amount of pump means(200); an injector(300); a circulating pump(400); a controlling panel(2); a monitoring system(1); and a supplementary storage tank. Overflow(100) which prevents overflow of stored fluorine is equipped with several storage tanks. Metering pump means locates the storage tank and the filtered water pipe(10) on the route. An injector is located on the route of a metering pump means and filters the water pipe. A circulating pump connected to an injector supplies water and fluorine solution with fluorine to the filtered water pipe. Controlling board and monitoring system controls to interlock the metering pump means and the circulation pump. A supplementary storage tank located between several storage tanks and metering pump means temporarily stores fluorine solution ejected from several storage tanks.
