What is the RDA of AP-24® Whitening FluorideToothpaste?

RDA (Relative Dentin Abrasivity) is the scale used to measure relative abrasivity of toothpastes. This scale starts at 0 and is open-ended. According to the American Dental Association, any product that falls below 250 is considered safe and effective for everyday use.

† The RDA value of AP-24® Whitening Fluoride Toothpaste is 103, which falls far below the 250 limit for daily use.

Relative dentin abrasivity (RDA) is a method of measuring of the erosive effect of abrasives in toothpaste on tooth  dentin.  It involves using standardized abrasives compared against the test sample. The determination of this value is done by determining the activity while cleaning worn dentin which is radioactively marked by mild neutron irradiation. The values obtained depend on the size, quantity and surface structure of abrasive used in toothpastes.

Abrasivity measurements are given by what’s known as an RDA value which stands for radioactive dentin abrasion or relative dentin abrasivity. The maximum value for FDA approval is 200. Toothpastes that claim whitening properties apear to have a higher abrasiveness index. Here is how to interpret the RDA values:

  • From 0 to 80 = low abrasion
  • 70 to 100 = midrange abrasion
  • 100 to 150 = highly abrasive
  • 150 to 250 = considered harmful to teeth

Are AP-24® products ADA approved?

AP-24® products are not ADA (American Dental Association) approved. There are no requirements for dentists to use ADA products, nor is ADA approval required to indicate a quality product.

What makes Nu Skin’s whitening technology different?
• No peroxides—they have the potential to cause tooth and  gum sensitivity.
• No harsh abrasives—they remove stains, but erode and scratch teeth.

Will AP-24® Whitening Fluoride Toothpaste make my teeth whiter than they are naturally?
No. AP-24® Whitening Fluoride Toothpaste is not an oxidiz-ing, bleaching agent (see above question). However, if your teeth are stained, darkened, or soiled from various foods, tobacco, or drinks, AP-24® Whitening Fluoride Toothpaste will quickly remove the stains and return your teeth to theirlight, natural color.
