The science behind Sensodyne: NovaMin Technology
![Flowchart explaining toothpaste effect](https://i-cf65.ch-static.com/content/dam/cf-consumer-healthcare/health-professionals/en_AU/sensitivity/Novamin_science_MOA.png?auto=format)
NovaMin works on contact with saliva to occlude exposed dentine by initiating a cascade of events at the surface of the teeth1–4
- 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.

NovaMin forms a robust hydroxyapatite-like layer over exposed dentine and within exposed dentine tubules2
