A method for repairing dentition, including milling beta tricalcium phosphate with sufficiently high energy to substantially distressed its lattice structure, mechanochemically chelating an edible acid thereto to yield functionalized calcium phosphate moieties, and incorporating the functionalized calcium phosphate moieties into an edible material to yield a calcium phosphate delivery system. The calcium phosphate delivery system is introduced into an oral environment and dentition is repaired. The functionalized calcium phosphate moiety is characterized by weakly bonded fumaric acid at least partially wrapped around distressed calcium phosphate particles, and dentition repair occurs at a dentition depth of at least 10 microns below the surface.
