Toothpastes That Eat Teeth

(thanks to Trish from the Aurum Group for supplying this information)

- see also Drinks That Eat Teeth -

The RDA value ( radioactive dentin abrasion or relative dentin abrasivity) is figured for every FDA approved toothpaste. However, this is rarely mentioned in the marketing efforts of the manufacturers, since a few of them are quite abrasive.
 
The ADA (American Dental Association) has adopted a standardized test. Basically, extracted human are irradiated with mild neutrons, mounted and stripped of enamel. The teeth are then inserted into a brushing machine and brushed at a constant pressure and stroke speed. The rinsewater is then measured for its radioactivity and recorded. Thus after a few calculations, a score or index is given to the toothpaste. Any value over 100 is considered to be abrasive. The ADA recommended limit is 250, whereas the FDA limit is 200. Other factors that are taken into consideration are the size, quantity, and surface structure of the abrasive itself.
 
The RDA table:
0-70 = low abrasive
70-100 = medium abrasive
100-150 = highly abrasive
150-250 = regarded as harmful limit

RDA Value
