Toothpaste featuring innovative PRO-ARGIN technology and offering a clinically-proven solution for the relief of tooth sensitivity pain. Exposed dentine tubules are the pathways to sensitivity pain: PRO-ARGIN technology plugs these tubules to start blocking sensitivity pain instantly. Over time, PRO-ARGIN builds a protective barrier that acts like a seal and prevents sensitivity coming back, even after exposure to amino acids. This layer of protection is rebuilt with every use of the sensitive toothpaste, ensuring long-lasting relief from tooth sensitivity.
