What is potassium nitrate? How does it stop sensitivity?
Potassium nitrate is a chemical compound. In toothpaste, it is the anti- sensitivity active ingredient that penetrates the exposed tubules (tiny holes) of the teeth to relieve the pain from sensitive nerves inside teeth. Additionally, it is one of the ADA-approved ingredients to treat tooth hypersensitivity.
