The present invention relates to compositions for mineralizing a dental surface, in particular tooth enamel. Methods of mineralizing hypomineralized lesions (including subsurface lesions) in the tooth enamel caused by dental caries, dental corrosion and fluorosis are also provided. In particular, the invention relates to a method of mineralizing a dental surface or subsurface comprising contacting the dental surface or subsurface with a compound that is capable of increasing or maintaining the pH of a solution and a mineralizing agent.本發明與礦化牙齒表面,尤其琺瑯質的組成物有關。也提供礦化琺瑯質中因蛀牙、牙齒侵蝕和氟斑引起之礦化不全病損(包括次表面病損)的方法。特別是本發明與一種礦化牙齒表面或次表面的方法有關,該方法包含以一能夠增加或維持一溶液之pH值的化合物及一礦化劑接觸牙齒表面或次表面。
