The science behind Sensodyne: NovaMin Technology

NovaMin formulations build a hydroxyapatite-like layer over and within dentine tubules

NovaMin is specially formulated in Sensodyne Repair & Protect to repair* exposed dentine:1–7

  • Once in contact with saliva, NovaMin initiates a cascade of ionic exchanges
  • This results in a rise in pH level in the localised environment, which allows NovaMin to bind to collagen fibres in exposed dentine
  • Once bound to dentine, NovaMin particles act as calcium and phosphate reservoirs, forming a robust and reparative hydroxyapatite-like layer over exposed dentine tubules to help protect against dentine hypersensitivity pain

*Forms a protective layer over the sensitive areas of the teeth. Brush twice a day for lasting sensitivity protection
