Lanthanum nitrate is a chemical compound primarily used in oral care products, particularly toothpastes, to help reduce tooth sensitivity. It works by forming a protective layer over exposed dentin tubules, blocking the pathways to the nerves and thereby decreasing sensitivity to hot, cold, or sweet stimuli. Its use is generally restricted to oral care applications.
