Sensodyne Science: Potassium Nitrate Formulations
Potassium nitrate formulations build protection over time to help desensitize nerves in tooth pulp3–6
Sensodyne potassium formulations contain 5% potassium nitrate. Potassium is an ingredient that is clinically proven to reduce dentine hypersensitivity:3–6
- Potassium ions can travel into exposed dentine tubules
- Build-up of potassium ions over time helps desensitize nerves in the tooth pulp, making them irresponsive to sensitivity stimuli

Potassium nitrate desensitizes nerves through the accumulation of potassium ions making nerves less responsive to potentially painful stimuli3–8
Potassium nitrate formulations work inside dentine to target the source of the sensitivity.3–8
