A method of treating teeth in dentistry, for the prevention of calculus, removal of caries, and dissolving of plaque, comprises bringing into contact with the teeth an aqueous solution containing a hypochlorite of an alkali and/or alkaline earth metal, and an amino compound capable of forming water-soluble non-mucous irritating N-chloro and/or N-dichloro derivatives thereof. The amine may be tertiary, or rearranged to result in a secondary or primary amine. Preferably an excess of amine to hypochlorite is used, to faciliate demineralization of old plaque and caries. For maintenance of the desired pH, a buffering system may be included. The solution may be used as a mouth wash, or in the form of a jet stream or a pulsated jet stream through an applicator such as a hypodermic needle, or with a carrier in the form of a paste for application with a brush.
A method of treating teeth in dentistry, for the purpose of prevention of calculus, removal of caries or dissolving plaque which comprises bringing into contact with the teeth an amount of an aqueous solution effective for such purpose containing the reaction product resulting from mixing a solution of (1) a hypochlorite selected from the group consisting of the hypochlorites of Li, Na, K, Rb, Cs, Ca, Sr and Ba and a solution of (2) ethylene diamine tetra acetic acid.
