Specifically, the reactive metallic oxide may be zinc oxide or the like, the polycarboxylic acid may be polyacrylic acid or the like, the reaction retarder may be calcium hydrogen phosphate or the like, and the coating film-softening agent may be polymethyl methacrylate or the like. The coated film formed from the tooth coating composition has a color approximate to the color of natural teeth, and causes little irritation to mouths. In addition, the coating film has high durability and easy removability after use, so that it can be easily used by ordinary consumers.</p> |
