  • Publication number: 20220117856
    Abstract: 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.
