The purpose of the present invention is to provide a dental material, and in particular a dental prosthesis, that has excellent hydrophilicity and that has excellent anti-fouling properties and the like. This dental prosthesis has a single-layer film that is obtained by curing a composition that includes: a compound (I) that has at least one hydrophilic group selected from an anionic hydrophilic group and a cationic hydrophilic group, and that has at least one functional group that has a polymerizable carbon-carbon double bond； a compound (II) that has two or more functional groups that have a polymerizable carbon-carbon double bond (provided that there is no anionic hydrophilic group and no cationic hydrophilic group)； and a surfactant (III) that has a hydrophobic part that comprises an organic residue, and that has a hydrophilic part that has an anionic hydrophilic group, a cationic hydrophilic group, or two or more hydroxyl groups (provided that there is no polymerizable carbon-carbon double bond).
