A novel dental composition is provided, which comprises; a combination of 8 to 92% by weight of liquid acid phosphates obtained by replacing one or two hydrogen atoms of orthophosphoric acid with alcohols having 3 to 13 carbon atoms and being essentially insoluble in water, and 92 to 8% by weight of at least one of reactive multivalent metallic salts selected from the group consisting of oxides, hydroxides, basic salts and silicates of alkaline earth metals, aluminium or heavy metals, said compounds being permitted to react with each other such that they are cured at room temperature. This composition may further contain liquid organic carboxylic acid having 6 or more carbon atoms, solid organic carboxylic acid having 5 or less carbon atoms and fluorine compounds in the form of fluorides silico fluorides titanium fluorides, and zirconium fluorides.
