The present invention provides a dentinal tubule sealing material excellent in durability of dentinal tubule sealing performance (acid resistance) and also in storage stability. The present invention relates to a dentinal tubule sealing material including tetracalcium phosphate particles (A), calcium hydrogen phosphate particles (B), calcium carbonate particles (C), and a non-aqueous dispersant (D), the dentinal tubule sealing material including 5 to 75 parts by weight of the tetracalcium phosphate particles (A), 10 to 70 parts by weight of the calcium hydrogen phosphate particles (B), and 2 to 50 parts by weight of the calcium carbonate particles (C) per 100 parts by weight of the total of the tetracalcium phosphate particles (A), the calcium hydrogen phosphate particles (B), and the calcium carbonate particles (C). |
