RDA is a widely accepted measure of toothpaste abrasivity. All Sensodyne toothpastes comply with the American Dental Association (ADA), Food and Drug Administration (FDA) and International Organisation for Standardisation (ISO) guidelines for daily use dentifrices.
Sensodyne toothpastes have RDA values in the range of 13-140, depending on the variants available in your country. Toothpastes with an RDA of up to 250 are considered suitable for everyday use.
