Did you know that baking soda has been used as a tooth cleanser for over 150 years?  Unfortunately, it got the reputation as being abrasive to the enamel.  Nothing could be further from the truth.  Usually toothpastes are rated on a scale from 0 – 200 according to their abrasiveness.  This is called the RDA value or “Relative Dentin Abrasiveness”.  Pure baking soda has an RDA of 7.  Did you know the closest RDA to this is 35, which is Arm & Hammer baking soda toothpaste?
