PROBLEM TO BE SOLVED: To obtain the subject composition containing a composite filler exhibiting a constant yellow color degree, giving a cured product having a nearly colorless and transparent color tone without deteriorating operability an mechanical strength, and capable of repairing teeth. SOLUTION: This curable composition comprises (a) a polymerizable monomer, (b) an inorganic filler having an average particle diameter of 0.01-1μm, (c) a composite filler having a yellow color degree of <=20 and comprising a polymer containing an inorganic filler having an average particle diameter of 0.01-1μm, and (d) a polymerization initiator in a (a)/[(b)+(c)]/(d) weight ratio of 100/(100-1000)/(0.1-5) and in a (b)/(c) weight ratio of 1/(0.2-3). The colored composite filler obtained by mixing the component (a) with the component (b), polymerization-curing the mixture and subsequently grinding the product is decolored with a peroxide into a yellow color degree of <=20. Thereby, teeth can be repaired with the nearly colorless and transparent repairing composition having an enamel color in the use of a dental composite repairing material.
