PROBLEM TO BE SOLVED: To obtain an oral cavity composition and composite particles for the composition further approaching the ideal state capable of satisfying high clearing capability and low wearability. SOLUTION: This oral cavity composition is formulated with integrated composite particles having an average particle diameter of 1-300μm e.g. through hybridization system so that a part of inorganic granular powder or organic fiber powder having an copper plate abrasion of <=30 mg internally sinks into the surface of nuclear particles consisting of water-insoluble or sparingly water- soluble high molecular substance.
