A non-aqueous tooth paste or gel composition comprising a peroxide selected from one or more members of the group consisting of urea peroxide, hydrogen peroxide, magnesium peroxide, calcium peroxide, lithium peroxide, sodium percarbonate, and ammonium persulfate; a bicarbonate salt; a peroxide stabilizer; and a hydrophilic, non-aqueous vehicle which is water dispersible, water emulsifiable or water soluble; wherein said bicarbonate is present in an amount effective to provide a neutral or basic pH when the composition is contacted with water; said peroxide stabilizer comprising a material selected from one or more members of the group consisting of a dessicating agent, a sequestering agent, colloidal particles, free radical preventatives, inorganic hardness salts, acidulating agents, and a coating on at least one of said peroxide and said bicarbonate salt that either readily dissolves, disperses or emulsifies in water; and wherein said peroxide, stabilizer and vehicle are present in amounts effective so as to inhibit decomposition of said peroxide during storage of said composition in a closed container, but so as to allow release of sufficient oxygen when the composition is contacted with water in the mouth to inhibit the motility of oral bacteria.
