The present invention relates to non volatile compositions that comprises: i ) from about 0.5 % to about 60 % by weight, of a silicone resin; ii) from abou t 0.1 % to about 30 %, by weight, of a silicon gum; iii) from about 0.1 % to about 95 %, by weight, of a non volatile polysiloxane fluid which has a viscosity from about 1cStk to about 1000cStk; and from about 0.01 % to about 50 %, by weight, of an oral care active selected from teeth colour modifying substances, anti-tartar agents, anti-plawue agents, fluoride ion sources, an ti- microbial agents, nutrients, antioxidants, H-2 antagonists, analgesics, anti - viral agents, mucosally absorbed pharmacological agents and mixtures thereof . A second aspect of the present invention relates to the user of non volatile oral care silicone compositions in the oral cavity to treat the hard and sof t tissue surfaces wherein the composition comprises: (i) from about 0.5 % to about 60 %, by weight, of a silicone resin; (ii) from about 0.1 % to about 3 0 %, by weight of a silicone gum; (iii) from about 1cStk to about 1000cStk. Compositions of the present invention are useful for providing a substantive composition on the surfaces of the oral cavity which can provide prophylacti c, therapeutic or consmetic benefits.
