Organic compounds from numerous substances such as drinks and tobacco cause discolouration of the tooth enamel.
Rapid White’s peroxide-free whitening system contains Sodium Chlorite (the accelerator). When it’s activated by the whitening gel or the dissolving strips, Chlorine Dioxide is released, which oxidizes the organic stains on the tooth surface (stains are destroyed and can be removed). The result is that teeth are whitened.
