Desensin® repair has a double desensitizing action because it is formulated with the innovative DENTAID nanorepair® technology, based on hydroxyapatite nanoparticles, and potassium nitrate, which inhibits the transmission of external stimuli to the nerve endings. Within the innovative DENTAID nanorepair® technology, hydroxyapatite nanoparticles, a natural component of teeth that ensures complete integration with the enamel, are deposited on the enamel surface, sealing the exposed dentinal tubules and forming a protective, wash-resistant layer that prevents the transmission of external stimuli that cause pain. Clinically proven: 95.45% of patients noticed a reduction in pain after the first application*.
