The present invention provides a preparation for attaching to teeth or tooth peripheries, which comprises a malleable oral composition and an active ingredient for intra-oral delivery. Further, the present invention provides a preparation for attaching to teeth or tooth peripheries, which comprises an oral composition in a hardening ointment-phase and an active ingredient for intra-oral delivery. The preparation of the present invention may give high adhesive force to the desired site in spite of gaps between teeth or curves of teeth. The preparation of the present invention having high adhesive force increases the time of adhesion to a target site in the oral cavity, and thus may be advantageous in achieving an intended effect.

Porous glass nanoparticles according to an embodiment have a specific surface area of 250 m2/g to 800 m2/g, and a pore volume of 0.1 cm3/g to 1 cm3/g. Since the porous glass nanoparticles have a high specific surface area and pore volume, the porous glass nanoparticles may have improved agilities to remineralize the demineralized dentin and occlude dentinal tubules. In addition, by including the porous glass nanoparticles, a dentin adhesive composition with improved adhesive strength to the dentin surface may be provided.
