Non-aqueous dentifrice compositions comprising a source of calcium ions and a source of phosphate ions such as a bioactive glass, a humectant such as glycerine, a hydroxyethyl cellulose polymer and a pyrogenic silica. The calcium source and the phosphate source together are precursors for the in situ formation of a desensitizing/remineralizing agent on teeth in the oral cavity. The compositions are useful in remineralizing teeth and in the treatment of dentine hypersensitivity.
