Abrasiveness Index of Common Toothpastes
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.

How do you rate Dr. Bronner’s cinnamon toothpaste?
Great question! Thanks for asking. As there are so many different types of toothpaste brands out there, we do not have the information for all of them on hand. We will work on getting this information for you and will let you know once we do
We reached out to the company to inquire about their RDA value. The company still has not gotten back to us. This could indicate they do not know the RDA value for their toothpaste. We looked up the ingredients in the toothpaste you asked about, Dr Bronner’s cinnamon toothpaste. It is fluoride free. We do recommend that if you are choosing a fluoride-free toothpaste, you look for a toothpaste that contains xylitol. We did not see xylitol listed as an ingredient in Dr Bronner’s toothpaste. Xylitol is a sweetener (sugar alcohol) that has positive dental benefits. Xylitol has been found to be promising in reducing dental caries and reversing the process of early cavities in studies. It is a great alternative for those wishing to choose fluoride free products. Some toothpastes that are fluoride free but contain xylitol are: Tom’s of Maine fluoride free toothpastes and Squigle Tooth Builder.

How about Hello toothpaste? I haven’t been able to find the RDA for that brand.
Last we checked with the company, they did not give specific values. They said their toothpaste is well within the ISO standard for enamel safety (This means less than 250).
Is Crest whitening strips bad for your teeth and gums?
As long as you use them as instructed on the packaging they are not harmful to your teeth or gums.
