The present invention provides an oral composition that can be used safely for a long time without any risk of occurrence of new crushing, and capable of polishing effect, preventing dental caries, and adsorbing / removing oral microorganisms and eating candy. An oral composition contains a porous carbon material having a specific surface area value of 10 m 2 / gram or more by nitrogen BET method and a pore volume of 0.1 cm 3 / gram or more by BJH method, or The total volume of pores having a specific surface area of 10 m 2 / gram or more determined by the nitrogen BET method and a diameter of 1 × 10 −9 m to 5 × 10 −7 m determined by the delocalized density functional method. Including a porous carbon material of 0.1 cm 3 / gram or more. [Selection] Figure 1 |
