RDA TOOTHPASTE ABRASIVENESS CHART

According to The Oral Health Research Institute, Essential Oxygen's Organic Low Abrasion Toothpaste is the lowest abrasion toothpaste available with a Relative Dentin Abrasivity (RDA) level of 12. That means Essential Oxygen's toothpaste is only slightly more abrasive than brushing with plain water.
The Essential Oxygen Organic Low Abrasion Toothpaste is the safest and most effective way to whiten your teeth without damaging healthy enamel.
