The science behind Sensodyne: Potassium Nitrate

Potassium nitrate formulations build protection over time to help desensitise nerves in tooth pulp3–6

Sensodyne Potassium formulations contain 5% Potassium nitrate. Potassium is an ingredient that is proven to reduce dentine hypersensitivity:3–6

  • Potassium ions can travel into exposed dentine tubules
  • Build-up of Potassium ions over time helps desensitise nerves in the tooth pulp, making them less responsive to sensitivity stimuli
Dentine tubules and potassium nitrate

Potassium nitrate desensitises 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
