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

Dentine tubules and potassium nitrate

Potassium nitrate desensitises nerves by exposing the nerves to potassium ions, making nerves less responsive to potentially painful stimuli.3–8

Potassium nitrate works inside dentine to target the source of the sensitivity.3–8
