Desensitising therapy – Where dentine hypersensitivity is a concern for the patient, the use of a 0.7% fluoride solution in the dental surgery followed by the home application of 0.4% stannous fluoride has been shown to be clinically beneficial. Potassium containing toothpastes are also considered to be appropriate for the management of sensitive dentine. Such agents may be applied with the aid of a custom fabricated bleaching tray (containing reservoirs). Tooth Mousse ACP (GC), contains ‘Recaldent’ which is an ingredient derived from casein (part of a protein found in bovine milk) that promotes remineralisation. This is a useful product for the passive management of tooth wear cases, when administered using a modified bleaching tray.
