Our toothpaste contains nanometric hydroxyapatite, allowing it to be deposited microscopically on the teeth. Over time, with routine use, it reduces sensitivity by slowly slowing down the daily loss of enamel, relieving discomfort or toothache. After months of use, you may notice the natural color and shine of your teeth. Continue brushing regularly, at least twice a day, with our nHAP toothpaste and you will see this improvement.
