The RDA scale was developed by the American Dental Association (ADA), government bodies and other stakeholders to quantify the abrasivity of a toothpaste. [21] It was not designed to rank safety of toothpastes, [21] and all toothpastes with an RDA of 250 or less are considered to be equally safe for regular use in terms of abrasivity. [22]
The abrasive effect of toothpaste is indicated by its RDA value. Toothpastes with RDA values above 250 are potentially damaging to the surfaces of teeth. The American National Standards Institute and American Dental Association considers toothpastes with an RDA below 250 to be safe and effective for a lifetime of use. [19]

Here the abrasiveness of toothpaste is detailed by its Relative Dentin Abrasivity (RDA) Sand, glass beads, metal pellets copper slag and dry ice may all be used for a process called sandblasting (or similar, such as the use of glass beads which is "bead blasting"). Dry ice will sublimate leaving behind no residual abrasive.
Causative factors have been linked to this condition and include vigorous, horizontal tooth brushing, using toothpaste with a relatively high RDA value (above 250), [11] pipe smoking or nail biting. It has also been shown that improper use of dental floss or Toothpicks can lead to wear on the interproximal (in-between) surfaces of the teeth. [2]
