Chemical action: Inhibits the transmission of signals that cause discomfort (Potassium nitrate) Physical action: Seals dentinal tubules and repairs the dentin surface thanks to DENTAID Technology nanorepair, based on nanoparticles of hydroxyapatite, a naturally occurring mineral in teeth, which ensures complete integration with tooth enamel by forming a stable bond with the hydroxyapatite of the teeth, relieving sensitive teeth from the first application. After brushing with VITIS sensitive toothpaste, a considerable number of the hydroxyapatite nanoparticles is deposited, sealing exposed dentinal tubules and thereby relieving sensitive teeth from the first application. Efficacy proven in scientific studies1,2,3: Relieves sensitive teeth in 95% of users from the first application 1. Gil Loscos, F; Iborra, I; Martí, M; Apliste, F.
