This slow release action formula gel toothpaste contains Natural substances and has a unique combination of active natural ingredients for sensitive teeth and gums. The slow release action formula is due to the presence of Carbossimetilchitosano, a substance that recent studies have shown helpful for preventing dental cavities and tartar. The blocking action remains on the gums and teeth and continues to be effective for at least 5 hours, which is the average time between teeth cleanings. This product contains Xylitol, a natural non-cariogenic sweetener that has the special quality of not fermenting when coming in contact with oral bacteria available in the mouth, therefore, it doesn’t allow for acids to form that corrode tooth enamel.
