How abrasive are ARM & HAMMER Dental Care®, PeroxiCare® and Arm & HAMMER® Advance White® products?
ARM & HAMMER® products are low in abrasion. That’s because they use ARM & HAMMER® Baking Soda as a primary cleaning agent. It is an old-fashioned misconception that Baking Soda is abrasive. In fact, baking soda is very low in abrasion.
The abrasive properties of a dentifrice are measured in a standard test called the Relative Dentin Abrasivity (RDA) Test, which is conducted by accredited facilities. The abrasivity of the dentifrices are recorded as RDA values and used by all toothpaste manufacturers. The higher the RDA value the more abrasive the dentifrice. In this test, baking soda alone scores a 7, and the ARM & HAMMER® products ranging from 10-117, all within accepted levels of abrasivity and typically below most other toothpastes.
ARM & HAMMER® Brand Toothpastes sometimes feels gritty. Will they hurt my teeth?
The grittiness is most likely the feel of the baking soda before it dissolves in your mouth. Rest assured that ARM & HAMMER® products are low in abrasion and will not harm your teeth.

I have been brushing with baking soda for more than 20 years. Last year I stopped using toothpaste altogether. At my last dental check-up, I asked the hygenist how my enamel looked. She said it was fine, no problems.
I haven't experienced calcium deposits and there is no calcium in baking soda, so I it's possible your calcium deposits were caused by something else.
I love the clean feeling of using baking soda. Plus, it's so cheap!
