Abrasives are the insoluble components added to toothpaste help the physical removal of stains, plaque and food debris. Abrasives also have property of stain removal or and cause whitening. Eg of abrasives: precipitated silica, alumina, dicalcium phosphate, dihydrate, calcium carbonate etc Abrasives (Whitening agents ) :
• Natural eg Hydrated silica, Calcium carbonate, Dicalcium phosphate dehydrate etc
• Chemical eg Hydrogen peroxide, Calcium peroxide, Sodium citrate, etc
Abrasive are available in various particle size. Different formulations contain different abrasive agents.
Relative Dentine abrasivity (RDA) is a numeric scale, which indicates the degree of abrasivity . A higher RDA value indicates a greater abrasive formula.

4) What is the role of Fluoride in toothpaste?

Today almost all toothpastes contain fluoride in one form or the other like: sodium fluoride, sodium monoflourophosphate and stannous fluoride. Most fluoridated toothpastes contain around 1000-1100 ppm fluoride.
Benefits:
1. Fluoride exerts its caries protective properties in several ways. Fluoride inhibits demineralization and enhances remineralization.
2. Fluoride makes the enamel structure more strong and resistant to bacterial acid dissolution.
