ABSTRACT:
A composition for the cleaning and protection of partial dentures and the associated natural teeth of the wearer consisting essentially of a peroxy bleach cleanser in an amount of from about 5.0 wt % to about 70.0 wt % of the total weight of the composition; a fluoride source incorporated in a polymer matrix in a polymer/fluoride weight ratio of from about 3:1 to 1:3; at least one surfactant in an amount of from about 3.0 wt % to about 18.0 wt %; an organic peroxy acid bleach in an amount of from about 10.0 wt % to about 40.0 wt %; an active bicarbonate-based effervescent agent in an amount of from about 5.0 wt % to about 65.0 wt %. The composition is formulated as a two-layer compressed tablet wherein one layer contains the peroxyacid bleach cleanser and surfactant while the other layer contains the fluoride and a surfactant. The partial dentures are oxidized by the peroxy bleach and they retain at least a portion of fluoride on the surface of the denture for the sustained delivery to the natural teeth once the partial denture is placed back into the mouth.
