To provide a tooth calcification agent having a high calcification effect on tooth surface calcification.
The tooth calcification agent comprises hardly-soluble calcium phosphate particles (A), a phosphorus-free calcium compound (B) and water (C). The particles (A) include at least one kind selected from the group consisting of anhydrous calcium hydrogen phosphate [CaHPO4] particles, α-tricalcium phosphate [α-Ca3(PO4)2] particles, β-tricalcium phosphate [β-Ca3(PO4)2] particles, amorphous calcium phosphate [Ca3(PO4)2 nH2O] particles, calcium pyrophosphate [Ca2P2O7] particles, calcium pyrophosphate dihydrate [Ca2P2O7 2H2O] particles, octacalcium phosphate pentahydrate [Ca8H2(PO4)6 5H2O] particles and calcium hydrogen phosphate dihydrate [CaHPO4 2H2O] particles. The tooth calcification agent comprises 30-76 wt.% of the particles (A), 0.001-4 wt.% of the phosphorus-free calcium compound (B) and 23-69 wt.% of water (C).
