Biofilm + sensitivity eliminator

A STAR product containing three powerful components:

Together, these have a powerful effect to provide instantaneous relief to hypersensitivity.

Increasing bond strengths of GICs

Pre-treating tooth surfaces with Riva Star is a great way to enhance bonding of glass ionomers to dentine6.


Riva Star is essential for clinicians practising Minimally Invasive Dentistry (MID)1-3,5. It conditions dentine and may assist tooth preservation.

Two years and beyond desensitising effect

Clinical studies support the immediate effect of Riva Star and its long term effect of over two years7.


Riva Star was designed by three renowned Australian clinicians, bringing together their clinical knowledge and experience of using these three exceptional components, and combining them into one STAR product – Riva Star!

Patented procedure

Unlike other silver fluoride systems, Riva Star’s two step patented procedure minimises the risk of staining. By applying the potassium iodide solution over the silver fluoride, a silver iodide creamy white precipitate is formed and washed off.


  • Desentising cervical tooth hypersensitivity.
  • Cavity cleansing

No Staining

Antibacterial Activity

Riva Star is an effective biofilm inhibitor. This is supported by study results from Otago University (NZ), that Riva Star has a higher inhibition zone against four bacterial species compared to sodium hypochlorite.
