NovaMin formulations
Sensodyne Repair & Protect and Sensodyne Complete Protection are specially formulated with NovaMin
Formulations with NovaMin form a protective layer over exposed dentine for lasting protection from dentine hypersensitivity.*1,2
*With twice-daily brushing
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
NovaMin forms a robust hydroxyapatite-like layer over exposed dentine and within exposed dentine tubules*1,2

NovaMin is a Bioglass that uses the natural building blocks of teeth3 to remineralise exposed dentine, forming a crystalline hydroxyapatite layer.1,3,6–11
- Calcium and phosphorous are the two main components of hydroxyapatite, the mineral which teeth are made of – this is key to the mode of action of NovaMin
-
NovaMin helps create a reparative layer that is structurally similar to dentine†1,12
The Ca:P ratio of the hydroxyapatite-like layer is ~1.67, similar to that of dentine and hydroxyapatite1
When overlaid, energy-dispersive X-ray (EDX) microscopy plots of the new reparative layer† (hydroxyapatite-like layer) and the dentine surface confirm their similar inorganic compositions.

A clinical study with continued twice-daily use of 5% NovaMin toothpaste demonstrated a reduction in the proportion of teeth with dentine hypersensitivity13,14
53% reduction in the proportion of teeth qualifying as sensitive in response to an evaporative air test (Schiff Sensitivity Scale) after 24 weeks of twice-daily brushing with Sensodyne Repair & Protect with 5% NovaMin.*13,14
Chart adapted from GSK Data on File RH0189713*Qualifying sensitive teeth met the following inclusion criteria: signs of EAR, GI ≤1, clinical mobility=0, no dentition exclusion and sensitivity to a qualifying air blast. ITT population (n=75)
-
A clinical study with continued twice-daily use of 5% NovaMin toothpaste demonstrated improvement in dentine hypersensitivity in response to tactile pressure†13,14
2.2x improvement in dentine hypersensitivity in response to tactile pressure after 24 weeks of twice-daily brushing with Sensodyne Repair & Protect with 5% NovaMin.†13,14
Chart adapted from GSK Data on File RH0189713†Maximum tactile pressure was 80g. An increase in tactile threshold indicates an improvement in dentine hypersensitivity. ITT population (n=75)
