Disclosed is a system and method for the delivery, into interdental spaces, of oral care active agents contained in particles. The particles are made of one or more superabsorbent polymers (SAP), and are of size generally small enough to be easily applied into an interdental space. To this end, the particles typically have a length of below 1.5 mm. By virtue of the SAP's ability of absorbing several times its own weight in water, the particles will swell once in contact with saliva. As a result, the volume of the particles as applied in between teeth increases by at least eight times, thereby effectively making the particles larger than the average interdental gap size. The particles, once swollen, are thus held more firmly between the walls of the interdental space, thus preventing them from being easily washed away.
Use of one or more polymer particles for the delivery of an oral care agent to an oral cavity of a subject, wherein the one or more polymer particles each:
Use according to any one of the previous claims, wherein the one or more polymer particles comprise the oral care agent.
Use according to 4, wherein the oral care agent is added to the one or more polymer particles within the applicator device prior to administration of the polymer particles to the oral cavity.
Use according to any of the previous claims, wherein the water absorbent polymer is a super absorbent polymer.
A use according to any of the previous claims, wherein the use is for maintaining or improving oral health of a subject
A system for the application of an oral care agent to an oral cavity of a subject, the system comprising:
A kit of parts for the application of an oral care agent to an oral cavity of a subject, the kit of parts including:
A preparation comprising one or more polymer particles for the delivery of an oral care agent to an oral cavity of a subject, the one or more polymer particles having an initial volume and at least one size dimension equal to or smaller than 1.5 millimetre;
A method for administering an oral care agent to the oral cavity of a subject, the method comprising:
