BAKING SODA
Baking soda, is our hero ingredient. It is a completely natural cleaning agent that is gentle on tooth enamel with an Relative Dentin Abrasivity (RDA) index value of 7.
The Relative Dentine Abrasivity (RDA) and Pellicle Cleaning Ration (PCR) graph below measures the erosive effect of dentifrices on tooth dentin and the ability of dentifrices on stain removal effectiveness. The lower the RDA value, the more gentle the paste is, whilst the higher the PCR, the better the cleaning effect.
All Arm & Hammer™
toothpastes are well below the FDA abrasivity limit and suitable for daily use, thanks to its high levels of Baking Soda producing the lowest RDA values, whilst providing a biological mechanism of deep action cleaning for superior plaque removal(1).
