A stomatological composition is provided. The stomatological composition is capable of stably compounding an antibody obtained from a hen egg yolk, and preventing diseases in an oral cavity such as odontonecrosis and periodontal disease from occurring, or improving such diseases in the oral cavity. The stomatological composition includes at least one selected from the group consisting of lipase, protease and the antibody obtained from the hen egg yolk, citric acid and a metal salt of citric acid. A total amount of the lipase, the protease and the antibody obtained from the hen egg yolk is in the range of 0.001 to 10 wt %. When an amount of the citric acid is defined as “A” [wt %] and an amount of the metal salt of citric acid is defined as “B” [wt %], the following relation is satisfied: 0.005≦A/B≦1. Further, the stomatological composition of the present invention includes a polyglyceryl fatty acid ester or an amino acid-based ampholytic surfactant as a surfactant. Further, the stomatological composition of the present invention includes a collagen.
