How Does Stannous Fluoride Reduce Sensitivity?

Anti-hypersensitivity: Stannous fluoride helps reduce teeth sensitivity resulting from hot, cold, acidic and sweet foods and beverages. It does this by forming a layer over open dentinal tubules (tiny channels in the dentin that lead directly to the sensitive pulp at the tooth's center).

How does fluoride reduce tooth sensitivity?

Fluoride is well-known for its benefits to oral health. Applied topically to the teeth, it remineralizes the tooth enamel (i.e. makes the teeth harder and stronger) to prevent sensitivity and tooth decay.

How does potassium nitrate help tooth sensitivity?

Potassium nitrate formulations build protection over time to help desensitize nerves in tooth pulp. Build-up of potassium ions over time helps desensitize nerves in the tooth pulp, making them irresponsive to sensitivity stimuli (e.g. cold water, hot coffee, etc.)
