Indaco presents the new chewing gum  COLFRESH  DENTAL BLACK, the first black chewing gum produced in Italy. The innovation is due not only to the unusual color but mostly to the special ingredients contained   in this product, first of all the activated charcoal,  then green tea and calcium. This formulation helps to stop plaque acid attacks and restores optimal pH levels in the mouth, increase the hardness of the tooth surface and rebuild the enamel. It also protects against the daily damage of tooth enamel and reduces oral dryness by moistening the mouth.  In additional the activated charcoal has “whitening” effect, by removing discolouration  without abrading or bleaching.
