Hydro-activated and/or oxygen activated aqueous, enzymatic, antimicrobial denture adhesive compositions are stabilized against enzymatic action prior to oral application of the adhesive by incorporating a thickene r into the adhesive formulation so as to provide the forrmulation with an enzyme immobilizing viscosity which inhibits enzymatic action during processing and in the adhesive package. An illustrative, thickened, enzymatic adhesive with th is enhancement contains glucose oxidase, glucose, lactoperoxidase and potassium thiocyanate together with a mixture of polyacrylic acid and polyvinylpyrrolidone in an amount to provide the adhesive with a viscosity o f at least about 300,000 centipoises.
