Toothpaste Protocol

Current abrasiveness of common toothpastes

Relative Dentin Abrasivity

  • The abrasives in toothpaste can wear away tooth structure
  • Once the enamel is worn, the next layer is called dentin. Dentin wears 7x faster than enamel
  • Enamel and dentinal abrasion can cause sensitivity in many patients
  • Each toothpaste is given a value known as RDA (relative dentin abrasivity)
  • We recommend an RDA of 50 or less
  • It is difficult to find out the RDA of toothpaste, as some companies do not disclose this information
  • We have a list of some toothpastes and their value

RDA Table:

  • 0 - 50 = low abrasive
  • 50 - 100 = medium abrasive
  • 100 – 150 = highly abrasive
  • 150 - 250 = regarded as possible harmful limit
