Dentaweiss Sub Zero Size - 125ml / 100ml / 50ml FLUORIDE: The fluoride contained in Dentaweiss reacts with the enamel to give it an acid-resistant protection. This helps to make the enamel stronger by reducing calcium and phosphate leaching, and also promotes remineralisation to reconstruct the crystalline structure of the enamel. PHOSPHATES: The monosodium and trisodium phosphates in Dentaweiss assist in the remineralisation process of the enamel by supplying phosphate ions and by providing the appropriate pH for the dentifrice to work. HYDRATED SILICA: Hydrated silica, derived from silicon dioxide, is a mild abrasive used in Dentaweiss as a mechanical cleaning agent to remove plaque, tartar and stains through its polishing action on the enamel.
