Toothpastes That Eat Teeth

Toothpastes That Eat Teeth:
(thanks to Trish from the Aurum Group for supplying this information)

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

    I thought about trying that stuff as my teeth are prone to cracking, but my dentist poo pooed the idea when I mentioned it to him. Has it seemed to make a difference for you? Not sure if there is anyway to tell that or not, at least not short term.

    Cool post, thanks for the info.
    Looks like Baking Soda's where my budget will be soon enough!
  • Connie JO4USA 2009/02/07 01:37:06
    You're more than welcome =) We used to use baking soda to brush with when I was a kid, looks like we might be going back to it now as well.

    I talked to my Dentist about the mouthwashes, gargles or whatever to use. Of course he recommended an $18 one from him. So I asked for his cheapest alternative.
    Salted water.

    $18??!!! good gravy, no way could I bring myself to pay that much for mouthwash! Makes sense that salt water would be a good alternative since it always seems to help soothe and heal a sore throat. I just might switch to that too as the alcohol in the regular mouthwashes can't be good for our mouthes. Thanks for the tip.
