Disclosed is a dissolvable film adapted to adhere to an oral mucosal tissue of a subject, wherein the film comprises at least three indigestible hydrophilic polymers constituting from 35% to 55% of the film dry weight and wherein the at least three polymers comprise xanthan gum and carboxymethyl cellulose (CMC) in a weight ratio of between 1:0.8-1.6, and at least one other cellulose based polymer. Optionally, the film may further include an active agent in an amount of 0.01% to 35% of the film dry weight. Disclosed also is a method for preparing the film and a method for treating or preventing oral conditions comprising implementing the film. Particularly, the film may be applied between dentures and the gums of the user.

The disclosed technology provides improved adhesive composition of use with dentures. These improved compositions include (a) a cross linked poly(acrylic) acid polymer, in combination with (b) a carbomethylcellulose (CMC) component and/or (c) an adherence promoting component. The compositions balance the many competing goals for effective denture adhesives, including adhesive strength and dispensing viscosity, without the need for zinc.

A dental adhesive comprises at least one polymerizable monomer, a polymerization initiator, and thermo-expandable particles comprising a shell encapsulating an expansion agent, the dental adhesive being characterized in that the shells of the thermo-expandable particles are made of a copolymer of acrylonitrile and methyl methacrylate.

A method of preventing or treating an oral disease by reducing adhesion of microorganisms, e.g. Candida albicans, to dental appliances fabricated and/or repaired by an autopolymerizing acrylic reinforcement resin comprising zirconium dioxide nanoparticles.
