PROBLEM TO BE SOLVED: To obtain tooth paste hardly causing the solidification or the like with time even if hydroxyapatite and sodium chloride are compounded so as to form high concentrations, and having stabilized physical properties. SOLUTION: This tooth paste contains hydroxyapatite and sodium chloride, and characterized by formulating neither a calcium salt of phosphoric acid nor a calcium salt of carbonic acid. The physical properties of the tooth paste can be improved by compounding at least one kind selected from a starch, a synthetic aluminum silicate, a natural aluminum silicate, and a crystalline cellulose, therewith.
