Curasept toothpaste contains a patented, clinically tested Anti Discolouration System (ADS) which, unlike other chlorhexidine mouthwashes, drastically reduce the appearance of brown-yellow spots which can form on the teeth due to chlorhexidine. Furthermore, Curasept's unique formulation helps prevent changes in taste. Curasept's formulation is sugar-free and it protects gums and teeth against the attack of harmful bacteria and the build-up of plaque.
