Abrasiveness Index of Common Toothpastes

S21

Relative Dentin Abrasivity (RDA) is a method of measuring the erosive effect of abrasives in toothpastes on tooth dentin. This value is necessary for FDA approval of the toothpaste but is usually not required to be disclosed on the label. In order to be FDA approved, the RDA must be 200 or lower. It is recommended to use a toothpaste with a RDA of 70 or lower. The lower the number, the less enamel/dentin will be worn away. The best way to know your toothpaste’s RDA is to ask the company. Here is a chart to help in understanding what the number means:

Table:

Low Abrasive:                                    0-70

Medium Abrasive:                           70-100

Highly Abrasive:                                100-150

Regarded as Harmful Limit:          150-250

 

This chart lists some common toothpastes that can be found in stores or online with their RDA value. This chart is courtesy of Kois Center located in Seattle, WA.
