Sensodyne Science: Potassium Nitrate Formulations

Potassium nitrate formulations build protection over time to help desensitise nerves in tooth pulp*3–6

Sensodyne potassium nitrate formulations contain 5% potassium nitrate, an ingredient that is clinically proven to relieve the pain of sensitivity with twice daily use:3–6

  • Potassium ions can travel into exposed dentine tubules3-6
  • Potassium nitrate works by depolarising sensory nerves in the tooth leading to them being less responsive3–6

*With twice daily use
