How Does Pro-Argin™ Technology Work?
CLOSEAn effective new technology that works differently
Hypersensitivity occurs when pain stimuli – such as cold, heat, air or pressure – trigger sensations that reach the intradental nerves through open tubules in exposed dentin.
Ordinary sensitive toothpastes with potassium salts work by numbing the pain. However, pain triggers can still reach the nerves via the open tubules.
Colgate® Sensitive Pro-Relief™ toothpaste plugs and seals dentin tubules, which helps block pain triggers to deliver instant and lasting relief.
