A tooth coating composition comprises a component A including a reactive metallic oxide; and a component B of water, which are mixed with each other when using the tooth coating composition, wherein at least one of the component A and the component B comprises a polycarboxylic acids, a reaction retarder and a coating film-softening agent. 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.

Tooth coating composition and over-coating composition therefor

A tooth coating composition contains shellac, solvent for the shellac, and mica titanium as the main constituents. The coating provided on teeth with such composition is excellent in its drying property, durability, color tone, and easiness of removal thereof. The content of the shellac in the whole composition is preferably from 6 to 12% by weight and the content of the mica titanium is preferably from 3.5 to 16% by weight.
