  • Tooth Bleaching Agent
    Publication number: 20090175917
    Abstract: The invention relates to “tooth-bleaching agent” compositions and to their applications in whitening teeth. The dental bleaching agent of the present invention comprises apatite, especially preferably in particle sizes in the nano range, likewise especially preferably in the form of fluorapatite. The tooth-bleaching agent can have a desensitising action and a positive action in respect of the remineralisation of the tooth surface.
