Abstract: A system for long term releasing of medication in the mouth, and especially an intra-oral fluoride releasing system (IFRS) for releasing fluoride over a long term for inhibiting the formation of caries in the teeth. The system uses a holder for retaining and protecting intra-oral fluoride tablets or other intra-oral medicament in the form of fluoride releasing devices (IFRD). The holder has a plate with retaining sides and retaining posts or a carrier. The tablet will fit within the holder. The tablet may be located in the carrier, or ligature bands can be tied around the tablet in order to releasably hold the IFRD within the holder. The system causes a level of fluoride to be maintained over a long term within the mouth which has been found chemically effective for caries control and without causing severe irritation to oral tissues.
